The front face carries IP20 protection; the terminals themselves are also rated IP20, so the part is suited for enclosed panel use where no washdown or dust ingress is expected.
Rated for motor switching at 4.5 kW on a 500 V 50 Hz supply and 5.5 kW at 690 V, this contactor handles typical three-phase induction motors up to that power band — think small conveyors, pumps, or fan drives. The AC-2 rating at 400 V gives 4 kW, which is the duty for slip-ring motors; the AC-4 rating at 400 V is 8.5 A, covering reversing or inching applications where the contactor makes and breaks under load. For DC switching, the 24 V coil draws 10 A, dropping to 2 A at 60 V and 0.3 A at 220 V — useful for braking or DC injection circuits.
Main circuit terminals are screw-type, accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid or stranded copper — the range covers most control panel wiring from signal-level to motor feeder. Type 1 coordination (contactor may need replacement after fault) allows a 35 A fuse.
The 57.5 mm height keeps it below common enclosure gland-plate clearances.
