Its 48–130 V AC/DC coil voltage span covers the common control supply voltages in most plants, so you don’t need a separate transformer tap. The built-in bidirectional peak limiting snubs voltage spikes at coil dropout, which protects the coil itself and keeps interference off the control wiring. Opening time runs 20–35 ms, closing 40–55 ms, and the mechanical endurance is 5 million cycles. That puts it in the range of a coil that’ll outlast the contactor in normal duty. Hold-in power is low – 4.4 W DC or 15.6 VA at 120 V AC – so the control transformer doesn’t need oversizing.
The coil operates over -13 to 140 °F ambient, with storage down to -76 °F. That’s enough for unheated panels in most climates. Pollution degree 3 (industrial) and IP20 mean it’s fine inside a cleanish enclosure but not out in the weather. The altitude rating – 3000 m without derating, 5000 m with a factor – says it works at most installations without fuss. Control circuit voltage limits: pick-up at 0.8–1.1 Uc, drop-out below 0.45 Uc.
