Tripping classes of the thermal overload relays

Standard classes in IEC 947-4-1 are classes: 10 A, 10, 20, 30. The tripping class indicates

according to IEC 947-4-1 the maximum tripping time in seconds under specied conditions of

test at 7.2 times the setting current and species tripping and non tripping times for 1.5 and 7.2

times the setting current. Mostly used class is 10 A.

Description

TA thermal overload relays are used with A Line contactors for the protection of

motors having a nominal voltage of up to 600VAC max per UL/CSA (690VAC and

800VDC per IEC).

Product range

• Standardrelays:

Types: TA25DU, TA42DU, TA75DU, TA80DU, TA110DU, TA200DU and TA450DU

– TA25 to TA110 and TA200 are directly connected in the motor circuit.

– TA450DU relays are fed through a linear type transformer

• Specialconstruction

Thermal overload relays with different certications and approvals.

Relays for protection EEx e motors.

Construction and function

• General

Thermal O/L relays and their accessories meet UL, CSA and most other important

international standards (IEC), European standards (EN) and the most important

national standards (DIN-VDE, NFC-UTE, BS, etc.). They meet the certication

and approval directives required throughout the world.

Thermal overload relays are 3 pole. The motor current ows through their bimetals

(1 per phase) which are indirectly heated. Under the effect of the heating, the

bimetals bend, cause the relay to trip and the position of the auxiliary contacts to

change.

The relay setting range is graduated in amps. In compliance with international and

national standards, the setting current is the motor nominal current and not the

tripping current (no tripping at 1.05 x setting current, tripping at 1.2 times setting

current).

The tripping curves (cold or warm starting, 3 phases and 2 phases) are shown on

page 2.14.

The relays are built to be self protecting in the event of an overload until the short

circuit protection device is activated.

Description

Application

Technical data

•Alltherelayshave:

– Free tripping: the resetting button, even if held in, does not prevent tripping of the thermal overload relay in the

event of a fault.

– Temperature compensation

– Phase failure protection according to IEC 947-4-1: Within the limits of the setting range, a reduced tripping time, and

thus improved motor protection, is obrtained in case of a phase failure.

– Tripping class: 10A, for TA relays

– Test functions and resetting: see table below.

• Auxiliarycontacts

The relays have two built in auxiliary contacts: NC marked 95-96; NO marked 97-98. Both contacts are physically separate

and can thus be used for 2 different circuits (control circuit and indication circuit).

Ambient temperature compensation

Thermal O/L relays are compensated against ambient temperature

variations by a compensation bimetal which is sensitive to the

ambient temperature.

Thermal O/L relays are designed to operate between –5 °C and

+40 °C in compliance with standard IEC 947-4-1. For a wider range

of –25° C to +55 °C consult the graph opposite.

Example:tripping at – 25 °C. Tripping takes place before 1.5 times

the setting current.

Resetting:TA25DU – TA450 DU thermal O/L relays have convertible

manual/automatic resetting.

Delivery:in manual resetting mode.

Technical data

TA25DU – TA450DU

Switchingfrequency:

To avoid untimely tripping, TA and T thermal O/L relays have been designed to withstand roughly 15 switching operations

per hour with an approximately equal distribution between working and rest cycles.

In these conditions, the motor starting time must not exceed 1 second and the starting current must be lower than or equal

to 6 times the motor In.

For intermittent operations, the diagram opposite species relay operating limits.

Example: Motor starting time: 1 sec.

Load factor: 40 %

Switching frequency: 60 ops./h according to diagram

For a higher number of operations and for load variations (e.g. frequent starting and braking), it is advisable to use

CUSTORAPID® protection.

For motors subject to particularly severe operating conditions (e.g. locked rotor) it is advisable to use protection combined

with a thermal O/L relay and the CUSTORAPID® system.

Protection of motors with long starting time

See electronic overload relay section, pages 2.21 - 2.32.

Mounting position

On a support at an angle of ± 30° in relation to the vertical plane (standard position).

Other mounting positions possible, except mounting on a horizontal plane (in this case the tripping

mechanism would be located above the bimetals).

Motor protection; Choice of protective device

Note:Fuses

Fuses do not protect motors against overloads. They are only used to protect installations and lines against short circuits.

To ensure efcient protection of a motor against short circuits, it is advisable to use aM type fuses in association with thermal

OLR relays.

For the selection of fuses or circuit-breakers, refer to the indications given in this catalogue concerning contactors on the one

hand and thermal O/L relays on the other.

In general, fuse protection for direct-on-line starting must be sized as follows:

– aM fuses: choose the fuse rating immediately above the full load value of the motor current.

– gG (gI) fuses: determine the fuse rating immediately above the motor current value and choose the next highest fuse rating.

Motor Protection — general

It is very important to choose an adequate protective device for the safety of the motor during operation and for its durability.

The efciency of protection methods varies according to the application. The overview below will help you to choose.

There is no general rule and we are available to advise you for special applications and especially in the case of difcult starting.

TA-DU thermal O/L relays are 3-pole with manual or automatic resetting mode selection.

The resetting button can also be used for stopping.

Built-in auxiliary contacts are physically separate and, consequently, can be used in different circuits (control circuit/indication circuit).

Each relay is temperature compensated and ensures phase failure protection.

Protective relays up to size TA75DU are protected against direct contact via the front face. Terminal shrouds are available for TA200DU to TA450DU size relays.

The connecting terminals are delivered in open position with (+,-) pozidriv screws and screwdriver guidance. It is advisable to tighten unused terminal screws.

Standard classes in IEC 947-4-1 are classes: 10 A, 10, 20, 30. The

tripping class indicates according to IEC 947-4-1 the maximum tripping

time in seconds under specied conditions of test at 7.2 times the

setting current and species tripping and non tripping times for 1.5 and

7.2 times the setting current. Mostly used class is 10 A.

Technical data

Terms and technical denitions

Altitude

Characterizes the place of use. It is expressed in meters above sea

level.

Circuits

• Auxiliary circuit – all the conductive parts of a contactor designed

to be inserted in a different circuit from the main circuit and the

contactor control circuits.

• Control circuit – all the conductive parts of a contactor (other

than the main circuit and the auxiliary circuit) used to control the

contactor’s closing operation or opening operation or both.

• Main circuit – all the conductive parts of a contactor designed to

be inserted in the circuit that it controls.

Insulation Class according to NFC 20 040 and VDE 0110

Characterizes adaptation of the devices to ambient temperature and

operating conditions. For given clearances and creepage distances,

a device will have different insulating voltages depending on

insulation classes A, B, C & D. Class C corresponds to most industrial

applications. The devices in this catalog belong to Class C.

Coordination of equipment protections during a short circuit

This is the addition upstream of the contactor and thermal overload

relay of a short circuit (SCPD) protection device such as a circuit

breaker, a fuse with a high breaking capacity or other fuses.

IEC publication 947-4-1 denes coordination Types 1 & 2:

• Type 1 – Coordination requires that, in the event of a short circuit,

the contactor or starter does not endanger persons or installations

and will not be able to operate without being repaired or parts being

replaced.

• Type 2 – Coordination requires that, in short circuit conditions, the

contactor or starter does not endanger persons or installations and

will be able to operate afterwards. The risk of contacts being welded

is acceptable. In this case, the manufacturer must stipulate the

measures to be taken with respect to maintenance of the equipment.

Rated operational current Ie

Current rated by the manufacturer. It is mainly based on the rated

operational voltage Ue, the rated frequency, the utilization category,

the rated duty and the type of protective enclosure, if necessary.

Conventional free air thermal current Ith

Current that the contactor can withstand in free air for a duty time of 8

hours without the temperature rise of its various parts exceeding the

maximum values given by the standard.

Cycle time

Cycle time is the sum of the current ow time and the no-current time

for given cycle.

Electrical durability

Number of on-load operations that the contactor is able to carry out; it

depends on the utilization category.

Mechanical durability

Number of no-current operations that a contactor is able to carry out.

Load factor

Ratio of the on-load operating time to the total cycle time x 100.

Switching frequency

Number of switching cycles per hour.
