The ground-fault monitoring version uses summation current formation on L + N conductor, so it detects leakage without a separate GFCI module. No undervoltage release or trip indicator on this variant, so if remote shunt-trip or local status indication is needed, step to a different order code in the 3VA family.","metaTitle":"Siemens 3VA2010-8KQ42-0AA0 SENTRON MCCB, 100A, 4-Pole, 440kA","metaDescription":"Siemens SENTRON 3VA2010-8KQ42-0AA0 molded case circuit breaker, 100A continuous, 4-pole, 440kA breaking at 240V.
