This is a line-protection design with an integrated ground-fault monitoring version that uses summation current formation on L+N conductor — useful for detecting leakage on solidly-grounded systems without a separate GFCI module. The 86 mm depth means it will clear most standard-depth enclosures, but check gland-plate clearance if the breaker sits near the back wall. ## Thermal and electrical limits Maximum power loss is 7.7 W — negligible for enclosure heat budgeting but worth noting for high-density panels. The initial trip setting is 20 A with a full-scale value of 100 A, suggesting an adjustable thermal-magnetic or electronic trip unit. No undervoltage release is fitted, and there is no trip indicator.","metaTitle":"Siemens 3VA2110-8KQ42-0AA0 SENTRON MCCB, 100A, 4-Pole, 440 k","metaDescription":"Siemens 3VA2110-8KQ42-0AA0 SENTRON molded case circuit breaker, 100 A continuous, 4-pole, 440 kA at 240 V.
