Rated breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, meaning it can safely interrupt fault currents up to those levels without welding contacts or cascading failure upstream.
The 70 mm depth (including terminals) and 110 mm height are standard for this class, so it clears most enclosure backplates and leaves room for wiring ducts. Ambient temperature range of -40 to 75 °C covers unheated warehouses and hot cabinet interiors alike; the 95 % humidity rating means condensation-prone environments are fine as long as the IP20 body (IP40 at the handle) is kept dry. The vibration resistance (50 m/s² at 25–150 Hz, 60 m/s² at 35 Hz for 4 s) means it holds up on machine-mounted subpanels near conveyors or compressors.
Integration notes
The sealable design (padlockable toggle) allows lockout/tagout without an external hasp. Halogen-free and silicon-free construction avoids corrosive off-gassing in sealed enclosures. Neutral conductor is not switched — this is a single-pole line-side breaker only.
