The AC-1 rating is the thermal current the main poles can carry continuously; for motor duty you'd need the AC-3 figure, which this part doesn't list. It's a big-frame unit: 438 mm wide, 332 mm tall, 238.6 mm deep, bolted to a plate, not snapped onto a DIN rail.
The coil is 380 V AC, 40-400 Hz, pulling 2200 VA inrush and 36 VA hold-in. Pick-up range is 0.85 to 1.1 times Uc at 55 °C; drop-out is between 0.3 and 0.5 Uc. That's a wide dropout band — the contactor stays pulled in down to about 114 V and drops somewhere between 114 and 190 V, which matters for brownout ride-through on a critical resistive load.
Short-circuit coordination and withstand
Associated fuse is 1600 A gG at ≤ 440 V. Short-time withstand current (Icw) is 10 kA for 10 s, 7.5 kA for 30 s, 5.5 kA for 1 min — that's the current the contactor can carry without welding during a fault before the upstream fuse clears. Rated breaking capacity is 2550 A per IEC 60947-4-1. Rated impulse withstand voltage (Uimp) is 8 kV, overvoltage category III, so it's suited for fixed-installation distribution panels.
Certified to EN 60947-1, EN 60947-4-1, IEC 60947-1, IEC 60947-4-1, JIS C8201-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1. Rated insulation voltage (Ui) is 1000 V per IEC, 1500 V per VDE 0110 group C. Protective treatment is TH for tropical environments.
