Product Overview
Providing expanded auxiliary contact capabilities, the Omron J77MN-20S side-mount unit adds switching channels to compatible motor protection circuit breakers. Auxiliary blocks are routinely integrated into motor control centers to relay status signals and interlock control logic with starter circuits. Pricing, availability and lead time are confirmed per enquiry through an RFQ.
