It is designed for motor protection, combining magnetic and electronic trip technology in a single device. Rated at 25 A continuous duty (In), it handles motor loads up to 7.5 kW at 400...415 V AC and up to 18.5 kW at 660...690 V AC, with a rated operational voltage (Ue) of 690 V AC and insulation voltage (Ui) of 800 V AC. The magnetic tripping window is set at 150...350 A, meaning it clears short-circuit faults fast while riding through normal motor inrush. Breaking capacity (Icu) reaches 120 kA at 240 V AC, 100 kA at 415 V, and 10 kA at 690 V, all per IEC 60947-2.
Electrical durability is 40,000 cycles at AC-3 with half rated current (In/2) and 20,000 cycles at full In at 440 V. That sets the service life expectation for a motor-starting application. Power dissipation per pole is 6.1 W, so total heat load in the enclosure is roughly 18.3 W at rated current. Factor that into your thermal budget — especially in a sealed, non-ventilated panel. Suitable for indoor panel mounting, not washdown environments. IK07 impact resistance handles routine panel knocks.
Compliance documentation includes EN/IEC 60947-4-1 and 60947-2 certification, fire resistance to 960 °C (IEC 60695-2-11), climatic withstand per IACS, and suitability for isolation per IEC 60947-1. That covers the main regulatory requirements for industrial control panels in most jurisdictions.
