Breaking capacity sits at 50 kA at 400 V AC, 100 kA at 240 V AC, and 10 kA at 500 V AC — numbers that tell you this breaker can handle a high-fault panel without cascading upstream. The 45 mm wide body snaps onto a 35 mm DIN rail (DIN EN 50022) and stands 97 mm tall by 96 mm deep, so it fits a standard enclosure footprint with room for side-by-side auxiliaries.
Panel Fit & Wiring
The 45 mm width leaves space for a full row of auxiliaries or a contactor alongside. Screw-type terminals on the main circuit accept 2x (0.5…1.5 mm²) solid or 2x (1…2.5 mm²) stranded; the auxiliary circuit uses the same terminal style. No side clearance needed, zero backwards clearance — you can pack it tight. Shock-rated to 25g / 11 ms, so it survives shipping and moderate vibration on a machine frame.
If you're driving a high-inertia load that needs a longer ramp, you'd step up to CLASS 20 or CLASS 30. Phase-failure detection is on by default — no extra module needed. Ground-fault detection is not included (that's a separate device if your application requires it). The auxiliary switch is transverse and field-installable, so you can add a remote trip-indication contact without pulling the breaker.
