SIRIUS Size S2 power contactor — 30 kW AC-3, screw terminals, DIN rail
The Siemens SIRIUS 3RT1036-1AF00-1AA0 is a Size S2 power contactor rated for motor switching at 30 kW on 500 V AC-3 duty, with a 22 kW AC-2 rating at 400 V and an AC-4 rating of 41 A at 400 V for reversing or inching applications. Maximum switching frequency varies by duty: 1000 cycles/hour at AC-1, 800 at AC-3, 400 at AC-2, and 300 at AC-4.
Wire termination and panel fit
Main circuit terminals accept solid conductors from 0.5 to 4 mm² (max 2x) and stranded from 0.75 to 25 mm² (2x), with a minimum 16 mm² at 40 °C ambient. Overall dimensions are 55 mm wide, 112 mm high, and 115 mm deep — the depth matters when fitting into shallow enclosures or behind gland plates.
