Breaking capacity — what it means for your fault bus
This breaker delivers 187 kA at 240 V, 121 kA at 415 V, and still 55 kA at 440 V — numbers that put it in the high-interrupting class for industrial switchboards where fault current can stack from multiple transformers or parallel feeders.
Fit and panel integration
The 184 mm width × 248 mm height × 110 mm depth footprint matches the 3VA2 platform, so if you're replacing a failed unit or adding a feeder in an existing SENTRON lineup, the bus-bar centers and terminal positions line up without re-drilling the backplate. Comes with 2 auxiliary switches (HQ type) and a shunt trip (STL) pre-installed — no field-kit wiring for remote tripping or status feedback. The front face is IP40 rated, enough for a clean indoor panel; keep it out of washdown zones unless you add a cover.
