Rated for motor and resistive loads
The LC1E1810B5: It also carries AC-1 and AC-3e utilisation categories, covering resistive loads and enhanced motor-switching applications respectively. The 24 V AC 50 Hz coil draws from a control transformer or separate control supply; the 1NO auxiliary contact provides feedback or interlock to the PLC or safety circuit. Non-overlap time between NC and NO poles is 1.5 ms guaranteed on both energisation and de-energisation, which matters for reversing or star-delta circuits where a short overlap would create a phase-to-phase fault.
Panel fit and environmental tolerance
Operating ambient is -5 to 55 °C, with coil rated voltage held at -20 to 70 °C — adequate for ventilated enclosures but not for direct outdoor exposure. IP2X means finger-safe but not sealed against dust ingress; the TH protective treatment (pollution degree 3 per IEC 60068-2-30) adds corrosion resistance for humid or condensation-prone environments like textile mills or food-processing washdown areas where the enclosure itself provides the IP65 barrier. Mechanical robustness includes vibration resistance of 1.5 Gn (contactor open) and 3 Gn (closed), plus shock survival at 7 Gn open and 10 Gn closed.
Compliance and lifecycle
Fire resistance tested to 850 °C glow-wire per IEC 60695-2-1 — the contactor housing will not sustain a flame under fault conditions.
