It is designed for motor protection in AC networks at 50/60 Hz, carrying motor power ratings of 22 kW at 400/415 V, 30 kW at 500 V, and 45 kW at 690 V. The utilisation category is AC-3 per IEC 60947-4-1, meaning it is built for starting and stopping squirrel-cage motors under load — the standard duty for a motor-protective breaker. Breaking capacity (Icu) is 100 kA at 230/240 V, 50 kA at 400/415 V and 440 V, 12 kA at 500 V, and 6 kA at 690 V.
The 55 mm width and 132 mm height fit a standard TeSys Deca footprint, so it occupies the same slot as other GV3L-family breakers in a panel layout. Connection pitch is 17.5 mm without spreaders — terminal lugs accept ring terminals torqued to 6 N·m. Operating temperature range is -20 to 60 °C, storage -40 to 80 °C, with an operating altitude limit of 3000 m.
Certified to EN/IEC 60947-2 (circuit-breaker standard) and EN/IEC 60947-4-1 (contactor-starter standard), plus UL 60947-4-1 and CSA C22.2 No 60947-4-1 for North American acceptance. Also complies with IEC/EN 60335-1 Clause 30.2 and IEC/EN 60335-2-40 Annex JJ for appliance applications. Suitability for isolation is confirmed per IEC 60947-1, meaning the breaker can serve as a visible-disconnect point in the motor circuit.
Durability and robustness
Rated for 50,000 electrical cycles under AC-3 at 415 V at full rated current, and 50,000 mechanical cycles. Mechanical robustness includes shock resistance of 15 Gn for 11 ms with contacts open, 30 Gn with contacts closed, and vibration resistance of 4 Gn across 5–300 Hz. Climatic withstand conforms to IACS for marine-environment humidity and salt fog.
