Product details

What the 10 A rating means on the line

The 3RH6122-1AP00 is a SIRIUS contactor relay, size S00, with 2 normally-open and 2 normally-closed auxiliary contacts.

Coil draw and wiring

The AC coil pulls 37 VA on pick-up and holds at 5.7 VA — that's about 0.16 A inrush at 230 V, so a standard 24 V control transformer or a PLC digital output can drive it without a separate interposing relay. No wire ferrule required for solid core; stranded needs a ferrule if you want a reliable termination in the screw clamp.
