Product details

SIRIUS Size S00 power contactor, 24 V DC coil

The magnet coil is rated 24 V DC, with a closing power of 2.3 W and holding power of 2.3 W — a DC-energised coil that stays latched on steady DC without the AC hum or inrush spike. Rated operational current at AC-12 (resistive) is 10 A at 24 V, and at AC-2 (slip-ring motors) it delivers 5.5 kW at 400 V. Main circuit connections use spring-loaded terminals, accepting 2x (0.25 to 2.5 mm²) solid or stranded conductors, or 2x (24 to 14 AWG). The IP20 finger-safe enclosure on the front and terminals suits installation inside a closed panel where no washdown or dust ingress is expected.

Coordination and short-circuit protection

This distinction matters when specifying the panel's SCCR and selectivity with downstream motor starters. Altitude rating extends to 2 000 m without derating.

Side-by-side mounting is permitted — the 6 mm spacing at the side is the minimum air gap for heat dissipation when multiple contactors are ganged on the rail.
