It carries a rated operational current of 110 A at up to 415 V AC, with 4 normally open main poles and a 220 V AC 50 Hz control coil. No auxiliary contacts are fitted on this variant.
Rated insulation voltage is 690 V, and the contactor can make 800 A and break 640 A at 440 V — figures that confirm it handles inrush and fault clearing within its AC-1 envelope. The control coil draws 200 VA inrush at 50 Hz and dissipates 6 to 10 W in steady state, which matters for transformer sizing in the panel.
Power terminals accept 4 to 50 mm² solid or flexible with cable end; control terminals take 1 to 4 mm². Tighten power connections to 12 N·m and control wires to 1.2 N·m — that torque on the screw clamp terminals keeps the joint stable under load cycling.
Compliant with EN/IEC 60947-1, 60947-4-1, and 60947-5-1, plus the Chinese GB/T equivalents. Protective treatment TH per IEC 60068 for tropical environments.
Durability and operating conditions
Rated for 350,000 electrical cycles in AC-1 and 3,000,000 mechanical cycles. Maximum operating rate is 1,200 cycles per hour at 60 °C. Withstands vibration up to 3 Gn when closed and shocks up to 7 Gn — figures that matter if the panel is mounted on a machine frame. Operating altitude goes to 3,000 m without derating.
