That steep curve at 690 V means this breaker is best applied on 400 V-class systems where its SCCR is highest. ## Thermal performance and ground-fault The ground-fault monitoring uses summation current sensing on L + N, so it picks up leakage on the protected circuit without a separate sensor. Power loss maxes at 10 W, manageable in a crowded panel.","metaTitle":"Siemens 3VA2110-5HM42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 150-","metaDescription":"Siemens 3VA2110-5HM42-0AA0 SENTRON MCCB, 100 A continuous, 4-pole, adjustable thermal-magnetic trip 150-1200 A, 187 kA at 240 V.
