Rated operational current is 0.4 A at AC-3 duty (400 V) — this is the motor-load switching rating, not a resistive-heater rating. The magnetic short-circuit release provides instantaneous protection against high fault currents; the thermal bimetallic element handles sustained overloads. Power loss is 5 W total typical.
The S00 frame occupies 45 mm width, 97 mm height, 96 mm depth — leaves clearance: 50 mm above and below, 30 mm at the sides, zero forward/backward clearance needed. Screw terminals accept 2×(0.75–2.5 mm²) solid/stranded or 2×4 mm²; torque to 0.8–1.2 N·m.
