Three-pole configuration, rated insulation voltage of 800 V, and a short-circuit breaking capacity that varies by system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. For a 415 V industrial feeder, that 52.5 kA SCCR gives real selectivity headroom against a downstream 25 kA MCCB — you can coordinate without oversizing the main.
That's a standard SENTRON 3VA form factor — it occupies the same footprint as other 3VA frame breakers. If you're swapping into an existing panel that was built around a 3VA1010 or similar, the mounting hole pattern and bus-bar spacing are identical; no re-drilling or re-bussing needed. The 76.2 mm width is three 25.4 mm pole pitches, so it aligns with standard 25 mm bus-bar centers. Maximum power loss is 21.7 W. In a sealed, non-ventilated enclosure, that heat has to be factored into the thermal budget — but for a panel with natural convection, it's manageable.
