Interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That SCCR headroom means it can sit upstream of a high-fault transformer or motor branch without cascading to the main breaker.
Physical fit — panel and DIN rail
The 105 mm width for a 3-pole 100 A frame is typical for this class — check your existing busbar or lug spacing if replacing a different brand. Max power loss is 13.5 W, so ventilation in a sealed enclosure is worth a glance if you're packing multiple breakers side by side.
What it does — and doesn't do
Ground-fault monitoring is built in (summation current on the L-conductor). Insulation voltage rated at 800 V. If you need a shunt trip, auxiliary contacts, or a communication module, this variant isn't it — you'd step to a different 3VA suffix.
