The 440 V AC coil at 60 Hz matches common North American control voltages; the built-in 1 NC auxiliary contact provides a feedback or interlock signal without an add-on block.
It also references EN/IEC 60335-1 Clause 30.2 and -2-40 Annex JJ for appliance applications. The protective treatment is TH (pollution degree 3) per IEC 60068-2-30, suitable for humid, non-condensing environments. IP2X finger protection is provided on the front face.
The non-overlap time between NC and NO contacts is guaranteed at 1.5 ms on both energisation and de-energisation, which ensures break-before-make in safety interlock circuits. Operating altitude is 3000 m without derating; ambient temperature range is -5 to 55 °C for operation, with storage from -60 to 80 °C.
