The Allen Bradley 140M-C2E-A16 is a motor protection circuit breaker designed for DIN rail mounting and rotary operation. It is rated for a current range of 0.16 to 1200 amps and is UL Listed/Recognized for motor loads. This circuit breaker provides short-circuit protection but requires separate overload protection. It features a visible trip indication, high current limiting, and high switching capacity.
The device is available with various auxiliary contacts and under voltage trips, making it suitable for a wide range of applications. It can be used in combination with a 100-C series contactor to create a Type F combination motor controller, providing complete short-circuit protection. The 140M-C2E-A16 is listed as a Manual, Self-Protected Combination Motor Controller by UL/CSA, which means it meets the necessary NEC/CEC requirements for the protection and control of individual Motor Branch Circuits without additional protective devices. However, at higher voltages and currents, it may only be listed as a Manual Motor Controller with optional approvals for Motor Disconnect and Group Installation, requiring the use of an upstream Branch-Circuit, Short-Circuit Protective Device (BCPD) in NEC/CEC Group Installations.
