Rated current is 0.16 A, with a thermal protection adjustment range of 0.1...0.16 A, meaning you can dial it down to match the motor's full-load current. This makes it suited for very small motors — fractional-horsepower pumps, fans, or conveyor drives on 50/60 Hz networks.
Where it mounts and how it connects
The 45 mm width and 78.5 mm depth fit standard enclosure layouts — no special spacing needed. Accepts horizontal or vertical mounting. Power circuit terminals accept snap-in connections: 2 cables of 0.5...2.5 mm² solid, or 0.5...4 mm² flexible without ferrule, or 0.5...2.5 mm² flexible with ferrule. That covers most control wiring gauges you'd run to a small motor starter. The IK04 impact rating means it can handle a 0.5 J impact, typical for accidental tool bumps during commissioning.
Listed as current production (active lifecycle stage). Complies with EN/IEC 60947-2 (circuit-breaker standard), EN/IEC 60947-4-1 (contactor/motor-starter standard), UL 60947-4-1, and CSA C22.2 No 60947-4-1. Also meets IEC/EN 60335-1 Clause 30.2 and Annex JJ for appliance applications. Phase failure sensitivity is built in — it will trip if one phase drops out, which prevents single-phasing damage on three-phase motors. Rated for uninterrupted duty per IEC 60947-4-1, meaning it can carry its rated current continuously without derating. Climatic withstand conforms to IACS, covering marine and humid environments.
Durability and environmental limits
Electrical durability is 100,000 cycles at rated current in AC-3 duty (motor switching). Mechanical durability matches at 100,000 cycles. That's a solid service life for a panel component — you'll likely replace the contactor before this breaker wears out. Withstands shocks of 30 Gn for 11 ms and vibrations of 5 Gn from 5 to 150 Hz. Fire resistance tested to 960 °C per IEC 60695-2-11. Power dissipation is 2.5 W per pole.
