What this insulated busbar fits
The Omron J77MN-CPM-3-45-5S is an insulated busbar designed to bridge power across the line side of Omron J7K series contactors, saving the wiring time and panel space of individual ring-terminal jumpers. It is listed under Circuit Breaker Accessories and Circuit Breaker Busbars, but its real job is on the contactor rail — it clips onto the J7K contactor terminals and carries the phase voltage between adjacent contactors in a group.
