Rated breaking capacity hits 100 kA at 400 V AC, 500 V, and 690 V — that is a genuine high-fault rating for a compact 65 mm wide device. Screw-type terminals for the main current circuit accept 2× (0.5…1.5 mm²) solid or stranded, or 2× (0.75…2.5 mm²) — sized for motor control wiring up to fractional horsepower.
Mounting and integration — DIN rail, clearances, orientation
Screw and snap-on fastening means you can pre-wire the breaker on the bench and clip it into the panel, or screw-mount it if the rail is full. Mounting position is any — horizontal, vertical, upside down — so it fits tight gland plates or vertical bus risers without derating. Clearance requirements: 50 mm upwards, 50 mm downwards, 30 mm at the side, zero forwards or backwards. The 97 mm depth and 65 mm width mean it occupies about the same footprint as a contactor of matching frame size — plan a 65 mm slot per motor branch on the DIN rail. That -20 °C floor is fine for most indoor panels but marginal for an unheated enclosure in a northern climate — if the panel sits below freezing at startup, the breaker will operate, but the motor current setting should be verified at ambient.
