In AC-4 duty at 400 V it carries 15.5 A, covering reversing and inching duty on squirrel-cage motors where the contacts see full locked-rotor current each cycle.
Side-by-side mounting is permitted, which keeps the rail density high when grouping multiple contactors in a motor control centre. Screw-type terminals on both the main current circuit and the auxiliary/control circuit accept solid or stranded conductors: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²) for the control wiring, and up to 2x 10 mm² for the main power wires. The pollution degree is rated 3, meaning the contactor is designed for industrial environments where conductive pollution may occur — no additional conformal coating required for a standard panel.
For Type 1 coordination (contactor may need replacement after fault), a 100 A gL/gG fuse is allowed. These values define the maximum short-circuit protection the contactor can withstand without welding or exploding; the actual fuse size should be selected per the motor full-load current and the coordination study for the panel. Above 40 °C, derating of the continuous current may apply — consult the thermal curve for the specific duty class.
