It carries an Icu of 150 kA at 415 VAC (50/60 Hz) per IEC 60947-2, which means it can safely interrupt fault currents up to that level without upstream cascading in a panel. The frame is isolation-rated (EN/IEC 60947-2) and accepts a separate trip unit (not included) to set the protection curve.
Breaking capacity and duty
At 440 VAC the Icu is 130 kA; at 220/240 VAC it reaches 150 kA. The Ics (service breaking capacity) mirrors the Icu at these voltages — 130 kA at 440 V, 150 kA at 380/415 V — meaning after interrupting a fault at those levels the breaker remains functional for immediate reclose. At 660/690 VAC the Icu drops to 20 kA, so for high-voltage applications verify coordination with the available fault current.
Fixed mounting on a backplate, 4-pole, 140 mm wide × 161 mm high × 86 mm deep. Front connection both sides, toggle control, neutral on the left. IP40 front face, IK07 impact resistance — suitable for enclosed panel installation where the front face is operator-accessible.
Environmental and electrical ratings
Rated insulation voltage 800 VAC, operational voltage 690 VAC, impulse withstand 8 kV. Class II shock protection on the front face. Mechanical durability 20,000 cycles; electrical durability varies with load — 10,000 cycles at 440 VAC at rated current, 20,000 cycles at half current.
