140M-I8P-D15S

The 140M-I8P-D15S Motor Protection Circuit Breaker (MPCB) is a high performance, high breaking, and compact circuit breaker that is available from Allen-Bradley/Rockwell Automation. It has a Size I frame, 3 poles, and 205 Amps of maximum frame current rating. The rated operational voltage of the motor protection circuit breaker is 600 Volts AC and the rated operational current is 150 Amps. This MPCB provides circuit protection with an adjustable magnetic trip. It weighs about 4.5 pounds. This circuit breaker is approved for use in group motor applications and it is possible to protect multiple motor branch circuits below a single short circuit protection device. The 140M-I8P-D15S Motor Protection Circuit Breaker (MPCB) acts as a protection device for electric motor applications while monitoring the electrical supply in the motor circuit.

The 140M-I8P-D15S Motor Protection Circuit Breaker is useful in industrial and construction applications, chillers, and compressors to prevent damages from short circuits. It provides protection against the line to line faults, phase loss faults, line to ground faults, and phase unbalance faults. The manual interrupt mechanism that is incorporated in this motor protection circuit breaker allows electric motors to be disconnected manually for standard maintenance or replacement work. Generally, this circuit breaker may be mounted in any position, up or down, horizontal or vertical, without affecting the tripping characteristics or the interrupting rating. The 140M-I8P-D15S motor protection circuit breaker provides motor overload protection, branch circuit protection, short circuit protection, and a motor circuit disconnect function. It has an adjustable magnetic trip mechanism to enhance the motor protection. Before installing the MPCB, make sure that the voltage and current ratings of the MPCB are compatible with the system it is intended for and with the motors that are being protected.
