140M-C-AFA10

Overview of Allen Bradley 140M-C-AFA10

The Allen Bradley 140M-C-AFA10 is an internal auxiliary contact block designed specifically for use with the 140M series motor protection circuit breakers, including the C, D, and F frame models. This component features a front-mounted design with one normally open (1 NO) contact and no normally closed contacts, allowing for straightforward signaling and auxiliary control functions. It does not add additional width to the circuit breaker assembly, maintaining a compact profile within electrical panels. Suitable for a variety of industrial motor control applications, the 140M-C-AFA10 enables enhanced monitoring and control capabilities, providing reliable auxiliary feedback for operational status. This product is discontinued as of March 31, 2024, with the recommended replacement being the 140MT-C-AFA10 model.

Applications / Use Case

The Allen Bradley 140M-C-AFA10 auxiliary contact block is primarily used in motor control and protection circuits where enhanced operational feedback is required. It is integrated with 140M series motor protection circuit breakers to provide status signaling for control circuits, allowing machinery supervision and automated response to breaker operations such as tripping or closing. Commonly applied in industrial automation, manufacturing plants, and processing facilities, it supports monitoring critical motors by feeding real-time circuit breaker position to PLCs, control relays, and alarm systems. This helps improve safety, maintenance scheduling, and operational efficiency by offering clear auxiliary signaling without the need for bulky add-ons.
