That AC-1 rating means it's designed for resistive loads — heaters, ovens, lighting banks — where the current stays steady through the switching cycle, not the inductive inrush of a motor start. The coil pulls 400 V AC at 40 to 400 Hz, with an inrush of 1100 VA and a hold-in draw of 18 VA once the armature seals. This is a plate-mount contactor, not a DIN-rail snap-on. At 233 mm wide, 238 mm tall, and 232 mm deep, it needs a bolted-down footprint in the panel — plan for the 35 N·m torque spec on the power circuit connections and the bar or ring-lug terminations that handle the 700 A path.
The headline number is 700 A at ≤40 °C in AC-1 duty. The associated fuse sizing is 500 A aM or 800 A gG at up to 440 V — a useful guardrail for the upstream protection. The closing time is 40 to 65 ms, opening 100 to 170 ms — that opening delay is inherent to the AC coil dropout characteristic. Heat dissipation runs 18 W for the coil and 88 W per pole in AC-1 service, so factor that into your enclosure thermal budget. The control circuit is screw-clamp terminals accepting 1 to 4 mm² flexible or solid wire. The power circuit uses bolted bar connections or ring lugs for up to 240 mm² cable — this is a high-current interface that needs proper lug crimping and the specified 35 N·m torque.
Standards and environmental limits
The contactor is certified to IEC 60947-1, IEC 60947-4-1, EN 60947-4-1, EN 60947-1, and JIS C8201-4-1. Rated insulation voltage is 1000 V per IEC 60947-4-1, with an impulse withstand voltage of 8 kV. Overvoltage category III. The front face with shrouds carries IP20 protection. Operating temperature range is -5 to 55 °C, storage from -60 to 80 °C, and it can operate at altitudes up to 3000 m without derating.
