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.
