SIRIUS S00 auxiliary contactor, 3 NO, 10 A
The 3RH2131-1AN00: It is designed for switching control circuits, signal interlocking, and extending the contact capacity of larger power contactors in a panel.
Panel fit and wiring clearance
The 73 mm depth and 57.5 mm height leave room for gland plates and wire bending. The auxiliary contact block is field-expandable (product extension auxiliary switch = yes), so you can add more NO/NC contacts on the same S00 frame without extra DIN rail space.
