The interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V and 440 V, and 187 kA at 500 V; at 690 V it drops to 3 kA, so for 690 V applications you need to check coordination with upstream devices. The breaker includes a communication function for integration into a monitored system and has ground-fault monitoring via summation current formation on the L-conductor.
That 105 mm width across 3 poles is the standard SENTRON 3VA footprint — it fits the same DIN-rail or mounting-plate cutout as other breakers in the family.
The maximum power loss is 7.7 W, which is modest for a 100 A frame and keeps heat buildup manageable in a sealed enclosure.
Protection and monitoring features
The ground-fault monitoring uses summation current formation on the L-conductor, which detects leakage by summing the phase currents; it does not require a separate neutral CT.
Environmental limits
That covers most indoor industrial and commercial environments, including unheated warehouses in cold climates. The -25 °C lower operating limit means it can be installed in a non-conditioned space in most temperate zones.
