The ABB 1SVR405658R6000 is a CR-MJ busbar jumper designed as a bridging accessory for the CR-M series of plugin control relays. Listed as a Type Relay accessory, its function is to electrically connect adjacent relay sockets on a DIN rail, creating a common potential rail without individual wiring per position.
This part carries a lifecycle stage of 'current', meaning it remains in ABB's active catalog for new builds and replacements.
Integration Note
Snaps onto the CR-M relay socket base before the relay is inserted, saving panel space versus daisy-chaining wires between adjacent sockets.
