The 115 V AC coil (40-400 Hz) pulls 2100 VA inrush at 20 °C; the control circuit holds within 0.85 to 1.1 Uc and drops out between 0.2 and 0.4 Uc. Three normally-open power poles, 1600 A rated operational current at ≤ 440 V AC-3, with a rated breaking capacity of 6240 A per IEC 60947-4-1. The 0.1 mOhm impedance at 1600 A 50 Hz means pole dissipation runs 60 W per pole in AC-3 and 250 W in AC-1 — heat that must be vented in the enclosure. Plate-mounted, 702 mm wide by 434 mm high by 255 mm deep. Power circuit bolted connections accept busbars up to 100 x 5 mm; control circuit screw-clamp terminals take 1 to 4 mm² flexible or solid. Tightening torque is 58 N·m on the power side, 1.2 N·m on control. IP20 front face with shrouds per IEC 60529.
Deployment context
This contactor is sized for heavy motor control in industrial panels — think large pumps, compressors, conveyors, or crushers on 400 V to 1000 V three-phase systems. The 3000 m operating altitude without derating suits high-altitude installations. Overvoltage category III means it is designed for fixed-installation distribution-level transients. The TH protective treatment indicates a tropicalized coating for humidity and corrosive atmospheres.
Certified to IEC 60947-4-1, IEC 60947-1, EN 60947-1, EN 60947-4-1, and JIS C8201-4-1. Rated insulation voltage 1000 V per IEC 60947-4-1, 1500 V per VDE 0110 group C. Associated fuse rating 1600 A gG or 800 A aM at ≤ 440 V. Mechanical durability 5 million cycles; maximum operating rate 600 cycles per hour at 55 °C.
