Allen-Bradley 140M-C-ASA11 Servo Drive Module

Allen-Bradley 140M-C-ASA11 is a side-mounted auxiliary contact block for Allen-Bradley 140M motor-protection circuit breakers. It provides an additional signaling contact that mirrors the breaker’s status, enabling simple indication, interlock, or sequencing signals in control circuits. The ASA11 accessory mounts on the side of the 140M frame and is designed to integrate with the 140M-C family to extend control wiring options without modifying the main power path. Common applications include PLC input signaling for breaker status, interlock circuits in machinery safety systems, or remote indicators in automation panels. As part of Rockwell Automation’s 140M ecosystem, the auxiliary contact ensures mechanical compatibility and electrical isolation between the signaling circuit and the main conductor, supporting straightforward wiring in standard control enclosures.
