The coil pulls in on a 42-48 V supply; expect operate times of 40-80 ms on both AC and DC, with an arcing time of 10-15 ms per break. That vacuum arc-quenching means the contactor handles the high inrush of motor starting without the contact erosion you'd see on a standard air-break contactor of similar frame size — useful for frequent starts or harsh environments where contact maintenance is a pain.
The Size S10 frame accepts stranded power cables from 70 up to 240 mm², so it's sized for high-current motor feeders or transformer primaries — not a small panel-mount relay. The coil termination is screw-type, which is standard for this class; the auxiliary switch block is included, with contacts rated 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V — enough for PLC inputs or pilot lights on the same control voltage. Switching frequency varies by duty: 750 cycles/hour in AC-1 (resistive) or AC-3 (squirrel-cage motor start/run), dropping to 250 cycles/hour in AC-2 (slip-ring motor) or AC-4 (plugging/inching). If your application needs frequent jogging, that AC-4 limit is the one that governs real life — not the higher AC-3 number.
Mounting and environment — panel integration notes
Mounting is screw-fixing through a single 11 mm hole, not DIN-rail snap-on, so plan for a drilled backplate or mounting channel.
