Product details

What this MCCB does on the line

The 3VA2140-0KQ32-0AA0 measures 105 mm wide by 181 mm tall by 86 mm deep — a standard 3-pole MCCB footprint for Siemens SENTRON 3VA2 frames.

Trip unit and protection features

The ETU860 electronic trip unit supports communication (via the integrated communication function) and ground-fault monitoring using summation current formation on the L-conductor. The N-conductor protection is adjustable from OFF to 40%–160% of the rated current, giving flexibility for 3-phase + N applications.
