Allen-Bradley 1494V-M40 Circuit Breaker Operating Handle

The Allen-Bradley 1494V-M40 is a flange-mounted operating mechanism for 3‑pole 1494V‑series circuit breakers, designed to convert a standard breaker into a manually actuated disconnect. As a functional device, the M40 mechanism must be used with a connecting rod, an operating handle, and a compatible circuit breaker; it is specifically used with Allen‑Bradley and Cutler‑Hammer 3‑pole breakers rated at 150 A, such as 140U‑I and 140M‑I families (EHD, FD, FDB, FDC, HFD, HMCP), in enclosures up to 24 inches deep. This device is part of the 1494V family and provides the on/off actuation for the configured breaker through flange-mounted installation. For installation, ensure the combination includes the correct connecting rod and operating handle for your enclosure and breaker model.
