The 1 NC auxiliary contact is built in, saving a separate aux block for basic feedback or interlocking. Rated operational voltage for the power circuit is 440 V, and the control circuit holds in from 0.7 to 1.3 times Uc (the rated control voltage) at 20 °C, dropping out reliably at 0.1 Uc below 50 °C. That gives you a solid 16.8 V to 31.2 V window on a 24 V nominal coil — forgiving on a sagging DC bus during a multi-contactor pickup. No screwdriver torque check, no loose strands — just strip 8 mm and push. Saves time on a rail full of contactors.
IP2X finger protection on the front means it's safe for open-panel builds behind a locked door, but it's not washdown-rated; keep it in a dry cabinet. Ambient temperature range of -25 °C to 50 °C covers most plant-floor conditions; storage from -50 °C to 80 °C handles warehouse extremes.
Global approvals are already in place: UL 60947-4-1, CSA C22.2 No 60947-4-1, IEC 60947-4-1, plus GB/T 14048.4 for China. Flame retardance meets UL 94 V1 and NF F 16-101/102. No separate certification wait for most markets.
Electrical durability at that load is 1.3 million cycles, and mechanical durability hits 30 million cycles, so it outlasts most machines in light-duty conveyor or pump service. Maximum operating rate is 3600 cycles per hour, fine for repetitive pick-and-place or valve sequencing. Coil inrush and hold-in power are both 1.8 W at 20 °C — that's the heat you need to budget in a sealed enclosure. Operating time: 10 to 20 ms to open the NO contacts on coil drop, 30 to 40 ms to close on energisation. Fast enough for safety interlocks when paired with a proper safety relay. Minimum switching capability for the signalling circuit is 5 mA at 17 V — so the NC aux can reliably wet a PLC input or a small relay without contact oxidation issues at low currents. Safety reliability is quantified: B10d of 1,369,863 cycles under nominal load per EN/ISO 13849-1, and 20 million cycles under mechanical load. That's useful for a risk assessment on a guard-monitoring contactor.
