Its rated current is 0.16 A, with a thermal protection adjustment range of 0.1...0.16 A and a magnetic tripping current of 1.93 A. This means it's sized for the smallest fractional-horsepower motors — think tiny fans, pumps, or conveyor drives drawing under 0.2 A full-load.
The 45 mm width means it takes a single modular space on the rail. Accepts power wiring up to 6 mm² solid or 4 mm² flexible with ferrule, torqued to 1.7 N·m. Horizontal or vertical mounting position, no derating needed.
Listed to EN/IEC 60947-2 (circuit-breaker standard) and EN/IEC 60947-4-1 (motor-starter standard), plus UL 60947-4-1 and CSA C22.2 No 60947-4-1. That covers the major North American and international regulatory jurisdictions. Also carries a 960 °C glow-wire fire resistance rating per IEC 60695-2-11. Phase-failure sensitive per IEC 60947-4-1, and suitable for isolation per IEC 60947-1.
