Rated for AC-3 duty at 11 kW at 690 V and 10 kW at 500 V, this contactor handles three-phase induction motors up to those power levels. Pollution degree 3 means it tolerates conductive dust and occasional condensation typical of factory-floor enclosures.
Screw-type terminals on the main circuit accept 2x (1 to 2.5 mm²) solid or stranded, up to 2x 10 mm² maximum. The auxiliary contact terminals take 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded. Strip and torque per the terminal markings — no special tooling needed beyond a standard screwdriver.
For Type 1 coordination (contactor may need replacement after a fault), a 63 A gL/gG fuse is permitted. This matters when specifying the branch circuit protection in a UL 508A or IEC 60947-4-1 panel. Electrical life will be lower and depends on the switching current and duty class (AC-3 vs AC-4).
