Manual motor protectors are electromechanical devices for motor and circuit protection. These
devices offer local motor disconnect means, manual ON/OFF control, and protection against short
circuit, overload, and phase loss conditions. Manual motor protection saves cost, panel space, and
ensures quick and reliable short-circuit protection by reacting within milliseconds. Close coupling
adaptors are available for combination with ABB contactors in various applications.

General information
Suitable applications

Single motor applications, suitable as motor disconnect
A manual motor protector is a simple, compact and economical alternative to conventional magnetic motor
controllers for local control of a single motor.

4

Upstream short-circuit and overcurrent protection in the form of either fuses or a circuit breaker is still required.
Manual motor protectors can replace the overload relay, contactor, and any wiring or components necessary for
controlling a contactor (i.e. pushbuttons) by utilizing the integral rotary handle for manual ON/OFF control.
Manual motor protectors also offer instantaneous (magnetic only) short-circuit trip functionality, allowing for
these devices to be utilized as UL 508/60947-4-1A circuit protectors.
MS Series Manual Motor Protectors are marked as “suitable as motor disconnect”, with the Types MS132 and
MS4xx not requiring additional accessories. This marking allows the devices to be utilized as local disconnects
within line-of-sight of the motor.

Group motor installation
Group motor installations utilize a single branch circuit protective device to protect multiple loads. Per NEC
Article 430.53(C), this branch circuit protection must be in the form of either fuses or an inverse-time (thermal
magnetic, MCCB) circuit breaker. Individual overload protection must be provided for each load. Devices
utilized in group motor installations must be marked as suitable in such applications.
Branch circuit protection for group motor installations is sized based on the sum of:
1. 250% (MCCB) or 175% (fuses) of the full-load current of the largest load in the group, plus
2. The sum of the full-load current of all additional loads
Conductors on the load side of the branch circuit protective device are sized in accordance with the full-load
current rating of said device.
In addition to meeting the requirements outlined above, Type MS132 devices are also suitable for tap conductor
protection in group installations as outlined in NEC Article 430.53(D), allowing the conductors on the load-side
of the branch circuit protective device to be sized no less than one-tenth (1/10) of the full-load current rating of
the protective device.

General information
Suitable applications
Combination motor controllers Types E & F
Combination motor controllers, as outlined in UL 508 Section 76, are a manufacturer’s tested combination of either individual
discrete components or a single controller. Fulfilling all the necessary components for a motor branch circuit, combination
motor controllers provide a disconnecting and load switching means, as well as overload and short-circuit protection. These
devices offer additional flexibility when selecting components for motor control and protection.

4

Combination motor controllers can also utilize busbar for self-protected, multiple motor installations. Busbar must be selected
and sized in accordance with the full-load current rating of the feeder circuit protective device.

Definitions
Type E Combination Motor Controllers are comprised of a UL 508 Disconnect, Branch Circuit Protector Device, Motor Controller
and Motor Overload typically included in a single Self-protected Control Device (manual motor protector). Following a shortcircuit fault, Type E Combination Motor Controllers are tested to operate for 6,000 electrical cycles, plus an additional 4,000
mechanical cycles, as outlined in UL 508 Table 83.1.
Type F Combination Motor Controllers are comprised of a UL 508 Disconnect, Branch Circuit Protector Device, and Motor
Overload typically included in a single Manual Self-protected Combination Controller with additional Magnetic or Solid State
Motor Controller utilized for remote operation (manual motor protector + contactor). The operational requirements following a
short-circuit fault differ for the manual motor protector and contactor.
