For a 4-pole block with no auxiliary contacts built in, this is a straightforward line-up contactor for heater banks, lighting, or transformer primary switching where the inrush is modest. The coil is 220 V AC 50 Hz, wide-range rated, with a dropout threshold of 0.3 to 0.6 Uc and pickup at 0.7 to 1.25 Uc. Inrush at 20 °C is 95 VA at cos phi 0.75; steady-state heat dissipation in the control circuit runs 2 to 3 W. That matters for panel thermal budgeting — a row of these on a DIN rail adds up.
Screw-clamp terminals on both power and control circuits accept up to 6 mm² solid or 4 mm² flexible with ferrule. Tightening torque is 1.2 N.m across the board. The IP20 finger-safe enclosure means it's for inside a panel, not washdown zones. Operating altitude to 3000 m without derating.
Protective treatment TH per IEC 60068 for tropical environments. Associated fuse rating is 40 A gG at ≤690 V, coordination type 1.
Durability and operating limits
Mechanical life is 10 million cycles; electrical durability in AC-1 is 300,000 cycles. Maximum operating rate is 1800 cycles per hour at 60 °C. Closing time is 12 to 22 ms, opening 4 to 19 ms. Vibration resistance: 1.5 Gn open, 3 Gn closed; shock: 7 Gn open, 10 Gn closed. That's robust for conveyor or pump panel cycling.
