Product Description
The Allen-Bradley 140M-C2E-B16 is a 3-pole, C-frame motor protection circuit breaker from the Bulletin 140M series, designed to provide disconnecting means, manual switching, overload thermal protection, and branch-circuit short-circuit magnetic protection for individual motor branch circuits. It features an adjustable thermal trip range of 1.0–1.6A and a fixed magnetic trip set at 13× the rated current (Ie), with a Class 10 trip curve. When combined with a compatible 100-C or 100-K series contactor, it is listed as a Type F combination motor controller for complete short-circuit protection. Suitable for use with AC motors, pumps, conveyors, compressors, HVAC equipment, and motor control centers.
