Rated at 0.8 A continuous current, it's sized for small motor loads up to 0.18 kW at 400 V AC (AC-3 duty). The headline number here is the 100 kA breaking capacity, which holds across the full voltage range from 240 V up to 690 V AC — that's a very high interrupt rating for a 0.8 A device, meaning it can safely clear a fault on a high-capacity transformer or a stiff industrial grid without the arc flashing over to adjacent gear.
Depth is 96 mm, height 97 mm. Screw-type terminals on both main and auxiliary circuits accept 2x (1... 2.5 mm²) solid or stranded, or 2x (2.5... 6 mm²) — also AWG 14–10. Strip length and torque per the nameplate; the dual-wire capacity is handy for daisy-chaining the line side without a separate terminal block.
Operating conditions and ratings
Shock rated at 25g / 11 ms — fine for most industrial machinery but not extreme rail or marine shock without additional damping. Power dissipation is 7.25 W in hot operating state (2.4 W per pole), so factor that into panel thermal calculations if you're packing several in a small enclosure. Maximum switching frequency is 15 operations per hour at AC-3 — that's typical for a motor-starting duty cycle; don't plan on rapid cycling like a solenoid.
