Raad recommended

Raad double level terminal blocks enjoy the spase-saving
advantage. It is remarkable in this type of terminal that the upper
level is offset laterally by half of the terminal block width. The
following advantages are met, due to the double wiring density:
Accessibility of the lower level screw is more effective with a screw
driver and
Lower labels and entry points can be viewed better
The EP3 end plate and the EP2 end plate compensates for the level
offset at the beginning and the end of the terminal strips, so that
standard terminal blocks can be directly aligned.
As for foot connection, they can be mounted on either of the TH 35
or G 32 mounting rails.

In accordance with the electrical standards, all electrical equipment
control systems and machines must be protected with fuse cartridges,
thus fuse terminal blocks have been developed to meet these standards
and requirements.
The technical data of the fuse terminal blocks, for the protection of
electrical devices, is bound to the application and the use of products.
In RCTF type, the fuse cartridge is inserted in terminal block together
with the screw cap. The terminal block is furnished with a light indicator
which signalizes when the fuse blows.
The RFT type holds different segments: The base terminal block and
the upper hinged-type fuse carrier.
The RFT type is equipped with indicator light, RCTF type alike,
functioning similarly. Another advantage of the RFT type which
distinguishes it from other types is its bonus to carry a spare fuse
cartridge inside the terminal cartridge.

RTP TERMINAL BLOCKS
Melamine moulded products are specialized to resist any deformation
effect and enjoy a very high tracking resistance .This resin has excellent
non-hygroscopic behavior with low humidity absorption, compared
to PA 6.6., having a higher continuous service temperature. Raad
melamine terminals are technically produced and best for working
sites which level of dryness and humidity is in variable conditions.
One disadvantage of melamine terminal blocks in comparison to the
PA 6.6 type is their low flexibility and their lack of disposable feature.
Raad melamine terminal blocks in RCT and RTM series are G32 mounting
rails mountable designed.

End Plate
The last terminal in a row must, in most cases, be covered with
an end plate. Within one terminal strip, composed of various terminal
sizes, end plates should also be interposed. The end plate external
dimensions correspond to the core dimensions of the attendant
terminal. The end plates are held by an end bracket.
Partition
Depending upon the operating voltage, a partition must be fitted
next to cross-connection groups, so that the necessary
clearance and creepage distance can be maintained.
Small Partition
Space-saving partitions can be post-fitted between cross-
connections for terminal blocks.
General Partition
These types of partitions serve for RTP16-50.

For cross-connection bar, connection sleeves and screws
are already captively mounted with the corresponding
number of poles. The cross-connection then only requires
inserting in the individual terminal row when fitting.
The cross-connection unit is supplied in 2, 3 and 10 poles.
Cross-Connection Bar
To handle cross-connection of several terminal blocks,
with the same potential, copper cross-connection bars
are used. These cross-connection bars supplied in 2, 3
and 10 pole lengths are equal to the individual terminal
widths. The cross-connection bar is electrically joined
through a connection sleeve to the terminal block bus
bar.
Connection Sleeve and Screw
The length of the brass connection sleeve is matched
to the individual terminal. In order to be able to connect
the cross-connection bar and the connection sleeve to
a terminal block bus bar, a brass screw is applied. The
cross-connections are designed so that where a terminal
does not need any cross-connection; it is possible to
remove the screw and its sleeve, thus no cross-connection
occurs in the terminal.

mountable electro technical and electric components.
Active and passive components are installed on
mounting rails. In control cabinet design, the TH 35-
15, TH 35-7.5 and G32 rails stand out with their high
degree of dimensional accuracy and surface tempering.
All steel versions are electroplated and additionally
passivised with a yellow chromate coating; comply
with the IEC 60715 standard. Raad supplies components
which are totally co-ordinated in their functionality.
The mounting rails can also be used as a protective
busbar. Raad protective conductor terminals meet the
requirements specified in IEC 60947-7-2.
The rails are both produced in slotted and unslotted
form for easier application by the users.

GENERAL TECHNICAL INFORMATION
Confidence in Connection
RAAD products use parts and materials conform to standards in electrical industry
and are subject to quality control system.
Metals
All metal parts in RAAD products are electro-plated using the latest state of
engineering.
The surface protection conforms to technical standards. Steel parts at the beginning
are zinc-plated and then a yellow chromate layer coats over the zinc, providing
the best possible passivation.
Copper and brass parts are tin-plated. Tin plating provides excellent protection
against corrosion and has good electrical conduction.
Insulating Material
RAAD terminal blocks use two kinds of insulating materials, thermoplastics and
thermosetting plastics.
Thermoplastics are processed using economical and environmentally healthy
injection molding processes, and have good recycling properties and can be
reused. Polyamide 6.6 is a thermoplastic, used in the insulation body of RAAD
products. This modern semi-crystalline material has excellent electrical, mechanical,
chemical and other characteristics even at 100 C for continues operating.
The short-time peak temperatures are permissible up to about 200 C and the
melting point is around 260 C.
Polyamide 6.6 absorbs moisture from its surroundings, on average 2.8 %. This
makes the PA 6.6 more flexible and resistant to breakage, even at -40 C. Today PA
6.6 is approved for use by the approval authorities such as CSA, NEMKO, KEMA,
PTB, SEV, UL, VDE, etc.
Thermosetting materials have high dimensional stability, negligible water absorption
and are tropic and termite resistant. Thermosetting plastic used by RAAD is a
melamine formaldehyde molding compound type MF 150, mainly organically filled
and is specified and tested in accordance with ISO, DIN, ASTM, JIS and BS. MF
150 has high continuous operating temperature, excellent inflammability and very
good tracking resistance.

GENERAL TECHNICAL INFORMATION
This is the most popular of all known methods of
connection. No other connection method allows such
high contact forces to be produced in such a small space
as a screw. RAAD terminal block screw connection is easy
to operate with a standard screwdriver, suitable for all
types of conductors without special preparation,
absolutely gas tight and vibrationproof.
Reliable clamping
Most RAAD products use a clamping unit system which
has been proven millions of times, world-wide. The
clamping units as well as clamping screws are produced
from hardened steel. When the clamping screw is
tightened, the resultant force causes the upper thread
overlap to spring open, thus causing a locking action to
be exerted on the screw and an excellent resistance
against vibration is achieved.

Terminal Blocks
Terminal blocks tests
IEC 60947-7-1 is the main standard which meets all types
of Raad terminal blocks. All Raad products are designed,
manufactured and tested in accordance with the standard,
which along with IEC 60947-1 determines the tests to be
conducted on terminal blocks, each as a type test.
Testsí details are specified in the standards. Below is an
abstract of the forgoing tests.
To assure the stability of the terminal block to its mounting
rail, with standard shape and dimension values, a relevant
test is conducted by inserting a 150 mm long steel pin
with a diameter specified in table 3 of IEC 60947-7-1. It
is connected to each clamping unit and a tightening torque
must be applied, as given in table 4 of IEC 60947-1. Force
must be applied to the pin with regular intensity and without
tears; the corresponding value must be taken from table 3
of IEC 60947-7-1. The distance between the application
point of the force and the centre of clamping unit must be
equal to 100 mm. During the test, no terminal block must
disengage from its mounting rail or suffer any damage.

Mechanical strength of terminals
To handle this test on screw-clamp terminal blocks, the
conductors must be used, which have the maximum cross-
section. The conductors must be connected and
disconnected five times depending on the screw clamping,
as determined in table 4 of IEC 60947-1. Where a screw
is loosened, a new conductor must be applied. During
the test, clamping units shall not work loose and there
shall be no damage that will impair the further use of the
screwed connections.
Table 3
Damage and accidental loosening of
conductors-flexion test
Specifically, this test is applied on terminal blocks suited
for the connection of unprepared round copper
conductors. It is a must to test both rigid and flexible
conductors with Min and Max cross-sections; optionally,
connections of multiple conductors to a single clamping
unit. A particular test apparatus is considered to aid the
test performance. During the test, neither must the
conductor slip out of the clamping unit, nor does breakage
occur near the clamping unit. Soon after the flexion test,

GENERAL TECHNICAL INFORMATION
a pull-out test must occur without restoring the initial
tightening torque.
Pull-out test
After the flexion test was conducted, a pull-out is carried-
out by force, the value of which is presented in table 5
of IEC 60947-1 to the conductor attached to the clamping
unit; this force must be applied regularly and without tears,
for 1 minute; for screw-clamp terminal blocks, the tightening
screws must not be newly tightened. During the test,
neither must the conductor slip out of the clamping unit,
nor does breakage occur near the clamping unit.
Rated cross-section
It is the value of max connectable conductor cross-
section. The rated cross-section shall be selected from
the standard cross-sections presented in table 1, IEC
60947-1. Where a ferrule is applied on a flexible conductor,
then a terminal block of one step higher rated cross-section
must be used, for example, a 2.5mm≤ flexible conductor
covered with the relating ferrule must be inserted to a one
step higher cross-section, i.e. terminal block with rated
cross-section 4mm.
Rated connection capacity
It is the value of max connectable conductor cross-
section. The rated cross-section shall be selected from
the standard cross-sections presented in table 1, IEC
60947-1. Where a ferrule is applied on a flexible conductor,
then a terminal block of one step higher rated cross-section
must be used, for example, a 2.5mm≤ flexible conductor
covered with the relating ferrule must be inserted to a one
step higher cross-section, i.e. terminal block with rated
cross-section 4mm.

The dash, when it appears, counts as a size when
considering connecting capacity (see 7.1.7.2).
Rated connection capacity
It is the range of cross-sections and the number of
connectable conductors based on which the terminal
blocks are designed. The IEC 947-7-1 determines the
relation between the rated cross-section and rating
connecting capacity of terminal blocks. Practically, terminal
blocks up to 35mm2, must be possible to connect a
conductor of cross-section equal to the nominal cross-
section and lower up to two cross-sections.
Insulation coordination for equipment
within low voltage systems
IEC 60664-1 deals with insulation coordination for
equipment within low voltage systems. It specifies the
requirements for clearances, creepage distances and solid
insulation for equipment based upon the performance
criteria. Terminal blocks standard, IEC 60947-7-1, has the
rules for coordination of insulation in accordance with IEC
60664-1.
Clearances
Degrees of pollution in the micro-environment
Pollution degree 1
No pollution or only dry, non-conductive pollution occurs.
The pollution has no influence.
Pollution degree 2
Only non- conductive pollution occurs except that
occasionally a temporary conductivity caused by
condensation is to be expected.
Pollution degree 3
Conductive pollution occurs or dry non-conductive
pollution occurs which becomes conductive due to
condensation which is to be expected.
Pollution degree 4
The pollution generates persistent conductivity caused
by conductive dust, rain or snow.
Overvoltage categories
Equipment of overvoltage category I is equipment for
connection to circuits in which measures are taken to limit
transient overvoltages to an appropriately low level.
Examples for such devices are protected electronic
circuits.
Equipment of overvoltage category II is energy-
consuming equipment to be supplied from the fixed
installation. Examples of such equipment are appliances,
portable tools and other household and similar loads.
Equipment of over voltage category III is equipment in
fixed installations and for cases where the reliability and
the availability of the equipment are subject to special
requirements. Examples of such equipment are switches
in fixed installation and equipment for industrial use with
permanent connection to the fixed installation.
Equipment of overvoltage category IV is for use at the
origin of the installation. Examples of such equipment are
electricity meters and primary over-current protection
equipment

Dielectric test
The test is conducted on 5 adjacent terminal blocks,
mounted on a metallic mounting rail and connected with
rated cross-section conductors.
Test voltage must have a sinusoidal waveform with a
frequency between 45 and 62 Hz.
The values applied, for 5 seconds, are those specified
in the table 12A, IEC 60947-1. Irrespective of glow
discharges without drop of voltage, no disruptive
discharges shall occur during the test.

Short-time withstand current
The standard IEC 947-7-1 obliges terminal blocks to
withstand a current equal to 120A per each square mm
of rated cross-section for 1 second.
Temperature-rise test
The current in a terminal block causes overheating due
to continuous operation. The overheating level shall not
overcome a specified value, thus a temperature-rise test
is applied to verify this performance requirement. The test
is conducted by means of temperature-rise test on 5
neighboring terminal blocks connected at a test current
as specified in table 4, IEC 60947-7-1. The temperature-
rise of any part of the centrally located terminal block shall
not exceed 45 K.

Voltage drop
Voltage drop at the terminal indicates an index of contact
resistance against the follow of current. The voltage drop
test is conducted before and after mechanical strength,
short-time withstand current and temperature-rise tests.
IEC 60947-7-1 states that the voltage drop, measured on
a new terminal block, must be lower than 3.2 mV and
after the tests lower than 150 % of the value measured
before the tests.
