It is rated for AC-3 duty up to 690 V, delivering 23 kW at 400 V and 40 kW at 690 V, so it handles pumps, conveyors, and compressors in that power band.
The AC-3 rating at 400 V (23 kW) is the motor-switching spec that governs real-world sizing. The 690 V insulation voltage gives headroom for line supplies without derating the basic impulse level. At AC-3 the maximum switching rate is 750 cycles per hour, so it keeps up with moderate cycling lines. For high-inertia loads or plugging duty, AC-4 rate drops to 250 cycles per hour — plan around that if your application reverses under load.
RoHS compliance date is May 1, 2012, which covers the EU RoHS 2 directive. The part carries no UL or CSA mark in the evidence, so verify acceptance for UL-listed panels if your spec requires it.
Screw terminals accept 2x (0.5 to 1.5 mm²) solid or stranded for control wiring, and 2x (16 to 12 AWG) for main contacts. The minimum permissible cross-section at 40 °C and 60 °C is 10 mm² — use ferrules on stranded to avoid strand fan-out under the screw.
