It carries a continuous current rating of 100 A at 40 °C ambient, with a thermal derating curve that holds 100 A up to 50 °C before stepping down to 91 A at 70 °C — useful to know if your panel runs hot. The interrupting ratings climb from 75.6 kA at 240 V through 52.5 kA at 415 V down to 11.9 kA at 690 V, so the SCCR headroom depends heavily on your system voltage.
At 130 mm high, 76.2 mm wide, and 70 mm deep, this 3-pole breaker fits the standard SENTRON 3VA mounting footprint.
At 240 V the interrupting capacity is 75.6 kA; at 415 V it is 52.5 kA; at 440 V it is 32 kA; at 500 V and 690 V it is 11.9 kA. These are the maximum fault currents the breaker can safely interrupt at each voltage level.
The breaker is rated 100 A continuous from 40 °C to 50 °C. At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. No derating is needed below 50 °C.
