The breaking capacity is 25 kA Icu at 415 V AC (50/60 Hz), which means it can safely interrupt fault currents up to 25 kA at that voltage without upstream devices needing to trip — a key figure for panel coordination studies.
This breaker is mounted on a backplate (mounting support: backplate) and can be oriented horizontally or vertically flat on the back. The front connections for both upside and downside make it suitable for panel builds with busbar or cable entry from the front. With IP40 protection and IK07 impact resistance, it is suited for indoor distribution panels where dust ingress and light mechanical impact are concerns.
Overvoltage category III makes it appropriate for fixed installations in building distribution boards. Operating altitude is 0...2000 m without derating; above that up to 5000 m derating applies. Electrical durability is 50,000 cycles at 440 V In/2 and 30,000 cycles at 440 V In; mechanical durability is 50,000 cycles. Neutral protection is set at 1 x Ir (4D). Earth-leakage protection is not integrated — if needed, an external Vigi module must be added.
