The interrupting capacity reaches 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V — figures that place it in the high-fault-current class for industrial distribution, suitable for transformer-secondaries and large motor branch circuits where fault levels are substantial.
Motor protection and trip features
The trip delay range spans 4 s minimum to 17 s maximum, which allows coordination with downstream motor starters and upstream feeders in a selective scheme — the short delay clears faults fast, the longer band rides through inrush without nuisance tripping.
The 3VA2110-7MN32-0JH0 measures 181 mm high, 105 mm wide, and 86 mm deep — a 3-pole frame that fits standard SENTRON mounting footprints and accepts busbar or cable connections on both line and load sides. The basic switch supplied is order code 3VA21107MN320AA0 — if you're replacing just the switching mechanism, that's the sub-assembly to source.
