It is rated for AC-2 duty at 22 kW at 400 V, covering slip-ring motor applications, and AC-3 duty at 30 kW at 500 V for standard squirrel-cage motors. At 690 V AC-3, it handles 11.4 kW. Its dimensions are 55 mm wide, 112 mm high, and 164 mm deep, occupying a single modular slot.
This is the rating that governs contact life under heavy switching — not the AC-3 figure. The AC-1 maximum operating rate of 1000 cycles per hour applies to resistive loads; AC-4 drops to 300 cycles per hour due to arc erosion. The auxiliary contact ratings cover a wide control voltage range: 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. The 24 V rating is the one to check for PLC-driven circuits — it confirms the contacts can handle typical 24 VDC solenoid loads without derating. This is standard for open panel mounting but requires the IP20 front cover for operator safety.
Main circuit terminals are screw-type, accepting 2x (0.75 to 25 mm²) stranded or 2x (0.25 to 2.5 mm²) solid. The 16 mm² minimum at 40 °C sets the smallest wire size for full rated current — use 16 mm² or larger for the power circuit to avoid terminal overheating. The IP00 terminal rating means the wiring area is not touch-safe — plan for finger-duct covers or shrouded terminals in the panel layout.
