140M-C-ASA20 Applications
This side-mounted auxiliary contact block adds status signaling to 140M motor protection circuit breakers, providing two normally open contacts for remote indication, interlocking, or control-circuit switching. Mounting on the right side of the breaker keeps the front face clear and preserves panel density. It fits C, RC, D, and F frame devices, giving a consistent accessory approach across a motor control lineup. Use it to signal breaker on/off state to a PLC, contactor coil circuit, or annunciator for improved monitoring and safety coordination.
