The auxiliary contact block 140M-C-ASA20 by Allen Bradley integrates into the 140M Circuit Breakers series. It offers enhanced capabilities for electrical systems requiring additional contacts for various automated tasks. This block is configured with two normally open contacts, providing the ability to manage multiple signals or functions simultaneously. The configuration supports side mounting, facilitating flexible installation in a range of setups.

Each contact block uses screw terminals, which ensure a secure connection for the wiring, thereby improving overall installation reliability. For operational performance, the block can handle up to 6.0 A at 24 V AC, making it suitable for substantial loads. Additionally, it supports 2.0 A at 120 V, 3.0 A at 240 V, and for DC applications, it accommodates 2.0 A at 24 V, along with 0.5 A at 110 V, and 0.25 A at 220 V DC. With a dual-pole configuration, this auxiliary contact block is adept at expanding the features of the main circuit breaker in industrial environments.
