SIRIUS 3RT1036-3XF00-0GA0 — Size S2 Power Contactor, Screw Terminals
It's rated for motor switching at 22 kW in AC-2 duty at 400 V, and 30 kW in AC-3 at 500 V. Side-by-side mounting is allowed, which saves rail space on a multi-contactor motor starter group.
Terminal Capacity & Wiring
The screw terminals accept solid conductors 2x (0.25 to 2.5 mm²) on the control side, and stranded 2x (0.75 to 25 mm²) on the main circuit. That's a wide enough range for most motor feeders up to the contactor's rating — 25 mm² stranded is good for about 85 A in practice, which covers the AC-4 current peak.
Mechanical & Electrical Endurance
The electrical switching rates are duty-dependent: AC-1 (resistive) allows 1000 cycles per hour, AC-3 (motor running) 800 cycles per hour, AC-2 (wound rotor) 400 cycles per hour, and AC-4 (plugging/reversing) 300 cycles per hour. Vibration resistance is 15 g for 5 ms and 8 g for 10 ms — enough for most industrial panels but not for direct engine-mount applications.
