The Omron J77MN-11F is an auxiliary contact block designed specifically for the J7MN series circuit breaker. It provides a set of normally open and normally closed contacts that signal the breaker's status — whether it's tripped or manually switched — to a PLC, indicator lamp, or safety circuit.
The J77MN-11F snaps onto the side of a J7MN circuit breaker. No tools needed — align the guide rails and push until the latch clicks. The contact block adds roughly the width of a standard DIN-rail mounted accessory to the breaker assembly. The contact marking is molded into the housing — common (C), normally open (NO), normally closed (NC) per the J7MN accessory standard.
