Coil is 220 V AC at 50 Hz, wide-range AC control. It pulls 160 VA inrush at 20 °C and settles to a heat dissipation of 6–10 W in the control circuit. Drop-out threshold is 0.3–0.6 Uc; pick-up is 0.7–1.25 Uc. That wide hold-in margin means the contactor stays closed through brief sags on a 220 V line — useful if your control transformer is feeding other loads.
Dimensions are 85 mm wide, 127 mm high, 125 mm deep — a standard footprint for a four-pole frame in this range. Tightening torque is 5 N·m on the power side, 1.2 N·m on control.
Durability and mechanical robustness
Mechanical durability is rated at 5 million cycles; electrical durability is 350,000 cycles at AC-1 load. Maximum operating rate is 1200 cycles per hour at 60 °C. Vibration resistance: 1.5 Gn contactor open, 3 Gn closed across 5–300 Hz. Shock resistance: 6 Gn open, 7 Gn closed for 11 ms. These specs mean the contactor can live on a high-cycle conveyor or compressor start-stop duty without premature mechanical fatigue.
Complies with EN/IEC 60947-1, EN/IEC 60947-4-1, EN/IEC 60947-5-1, plus the GB/T equivalents for China. Protective treatment TH conforming to IEC 60068-2-30 (damp heat cyclic). IP2X finger protection on the front face.
