Rated for 100 kA SCCR at 400 V and 500 V, and 10 kA at 690 V, this breaker can safely interrupt high fault currents without upstream damage. The high interrupting capacity makes it suitable for installations with large transformers or strong utility feeds. Screw-type terminals on the main circuit accept 2× (0.75–2.5 mm²) solid or stranded, or 2× 4 mm² — straightforward for a panel builder.
No ground fault detection on this variant; if that's needed, look at the -Z or -ZR suffix options. Temperature compensation is active across the operating range, keeping the thermal trip curve stable regardless of enclosure heat buildup. Mounting position is any — horizontal, vertical, or flat — so it fits tight enclosures without derating the trip settings.
