The 100 A full-scale value and 20 A initial trip threshold mean it is sized for a 100 A feeder or large motor branch, with the adjustable thermal-magnetic trip unit allowing coordination downstream. Breaking capacity is the headline: 330 kA at 240 VAC, 242 kA at 415 VAC, and 242 kA at 440 VAC, dropping to 187 kA at 500 VAC and 3.7 kA at 690 VAC. The ground-fault monitoring version uses summation current formation of L + N conductors, meaning it measures vector sum of phase and neutral currents to detect leakage. That is a fit for TN or TT systems where residual current detection is needed at the breaker level without a separate RCD. Dimensions are 86 mm depth, 140 mm width, 181 mm height. At 140 mm wide for a 4-pole, it fits standard Siemens SENTRON panel mounting footprints; the 86 mm depth leaves clearance for rear-connected busbars or cable lugs in a typical 200 mm deep enclosure. Maximum power loss of 10 W means minimal heat contribution inside a sealed panel — no forced ventilation required for this single breaker.","metaTitle":"Siemens SENTRON 3VA2110-7HM42-0AA0 MCCB, 100 A, 4-Pole, 330","metaDescription":"Siemens SENTRON 3VA2110-7HM42-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, 330 kA at 240 VAC.
