Its 6 A rated operational current at ≤440 V AC handles small motor loads: 1.5 kW at 220–230 V, 2.2 kW at 380–415 V, and 3 kW across the 440 V to 690 V range. The 440 V AC coil pulls in on that voltage, and the built-in 1 NC auxiliary contact gives you a feedback or interlock path without adding a separate block.
The 3-pole, 3 NO contact arrangement leaves no normally-closed power poles; the single NC auxiliary is on the control side. Spring-cage or screw terminals depending on the variant; this order code carries the 440 V AC coil, so verify coil voltage matches your control transformer tap before landing wires.
