Product details

What this SIRIUS S12 power contactor is

It uses a 380-420 V AC coil and mounts via screw fixing to a vertical surface, rotatable ±90° or tiltable ±22.5° front-to-back.

Dimensions are 214 mm high, 160 mm wide, 225 mm deep. Main power conductors accept stranded cable from 70 to 240 mm². The coil connection uses spring-type terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded wire. A single 11 mm mounting hole is provided for the screw fixing.

Switching performance by duty class

Maximum switching frequency varies by duty: 700 operations/hour in AC-1 (resistive), 500/h in AC-3 and AC-3e (standard motor starting), 200/h in AC-2 (slip-ring motor), and 130/h in AC-4 (plugging/inching). Rated auxiliary contact currents: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V.
