Rated for AC-3 duty at 800 cycles per hour — that's the motor-switching rhythm for conveyors, pumps, compressors. At 400 V AC-2 it handles 22 kW, so it's sized for a 30 kW motor at 500 V (AC-3, 50/60 Hz). The arcing time sits at 10 to 15 ms, and the coil operates across 0.8 to 1.1 x rated voltage at 50 Hz.
Wiring and terminal capacity
Main circuit terminals accept solid wire 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). That covers common motor leads up to 4 mm² solid or 25 mm² stranded — no need to crimp ferrules for the stranded side if you're comfortable with screw clamps. The front is IP20 (finger-safe), the terminal area is IP00 (open to the panel environment).
