What this coil is for
It's the part you swap when the original coil opens or shorts — not a contactor body, just the electromagnet that pulls the main poles in. Rated for continuous duty at 850 V AC, 50 or 60 Hz. No built-in suppressor module, so if your circuit needs RC snubbing or varistor protection, you add it externally across the coil terminals.
Durability and operating rate
Rated for 5 million mechanical cycles — that's the coil plunger and armature wear life, not the contactor's electrical endurance under load. Electrical life will be lower depending on the switched current and duty class. Maximum operating rate is 1200 cycles per hour at 55 °C. Above that temperature, derate the cycling frequency to avoid coil overheating from the cumulative I²R heating.
