Product details

SIRIUS S2 power contactor for motor switching

Its 24 VDC coil draws 10 A at rated voltage, and the contactor is rated for 30 kW at 500 V AC-3 duty — the rating that governs motor switching. At 690 V AC-3 it delivers 11.4 kW, and at 400 V AC-2 it handles 22 kW.

Main circuit terminals are screw-type, accepting 2x solid conductors from 0.25 to 2.5 mm² or 2x stranded from 0.75 to 25 mm². The minimum permissible cross-section at 40 °C is 16 mm². Coil terminals accept 2x solid or stranded 0.75 to 16 mm².

Switching frequency and environmental limits

Maximum switching rates: 1 000 cycles/hour at AC-1, 800 at AC-3, 400 at AC-2, and 300 at AC-4. Mechanical life is typically 10 million operations.
