The Siemens 3RT1036-1AC10 is a SIRIUS power contactor in the S2 frame size, rated for 22 kW at 400 V in AC-2 duty — that's the motor-switching category for slip-ring motors and moderate inrush loads, not the heavier AC-3 across-the-line start.
Side-by-side mounting is permitted. Degree of pollution is 3. Front protection is IP20; the terminal area is IP00.
Switching performance and auxiliary ratings
The contactor's mechanical life is typical 10,000,000 operations. Maximum switching frequency varies by duty: AC-1 (resistive) at 1,000 cycles per hour, AC-2 at 400, AC-3 at 800, and AC-4 at 300. The coil is rated 24 V at 60 Hz, with a voltage tolerance of 0.8 to 1.1 times rated at 60 Hz. For auxiliary contact ratings: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, 3 A at 400 V, and 30 kW at 500 V, 11.4 kW at 690 V — these are the switching capacities for the built-in auxiliary contacts, not the main pole ratings.
