The 3RT1036-1AP05 is a SIRIUS power contactor in size S2, rated for motor loads up to 30 kW at 500 V and 11.4 kW at 690 V. It handles AC-2 duty at 22 kW and AC-4 at 41 A, both at 400 V — so it's suited for slip-ring motors or reversing applications where the switching cycle sees full load current.
The 65 mm width and 112 mm height fit a standard enclosure layout, and the IP20 front means it's safe for open-panel wiring as long as the live terminals are guarded.
The 3RT1036-1AB00 is the same size S2 contactor but with a different coil voltage or termination variant. It will drop into the same DIN-rail footprint and panel cutout, but verify the coil rating matches your control circuit before swapping. The 3RT1036-1AP05 uses a screw-type main terminal; if the 1AB00 has a different termination (e.g., spring-cage), that changes the wiring prep.
The part carries a RoHS compliance date of May 1, 2012, and is designed to IEC/EN standards for industrial control equipment. UL and CSA listings are typical for the SIRIUS series, though the specific approvals for this order code should be confirmed against the project's jurisdiction.
