It combines a thermal overload relay (Class 10) with a magnetic short-circuit trip in one 3-pole package, rated at 2.5 A operational current and 690 V maximum. The 2.5 A figure is the AC-3 motor rating at 400 V — the one that governs real motor switching duty, not the resistive-heater curve.
Size S00 footprint: 45 mm wide, 97 mm tall, 96 mm deep. Any mounting position is permitted. Screw-type terminals accept 2x (0.75 to 2.5 mm²) solid/stranded or 2x 4 mm², torque range 0.8 to 1.2 N·m.
The magnetic short-circuit release handles instantaneous faults. Rated surge voltage resistance is 6 kV, and the breaker withstands 25 g / 11 ms shock per IEC 60068-2-27. Relative humidity tolerance is 10 to 95 %.
