Breaking capacity is 121 kA at 240 VAC, 75.6 kA at 415 VAC, and 52.5 kA at 440 VAC — figures that give headroom for high-fault installations without cascading upstream. Insulation voltage rated 800 V. The breaker carries one auxiliary switch and one trip alarm switch (HP design) for remote status indication.
Fits standard SENTRON panel-mount cutouts and busbar systems. Current derating begins above 55 °C (31 A at 55 °C, 30 A at 70 °C). Ambient derating is the main constraint for dense panel layouts.
