The interrupting ratings tell you where it fits: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The ETU860 release is a communicating electronic trip unit, so this breaker supports ground-fault monitoring via summation current formation of the L + N conductor. The insulated voltage (Ui) is 800 V, which governs the insulation coordination for the buswork it connects to. Power loss maxes at 10 W, manageable for thermal calculations in a dense cabinet. ## Physical fit That 140 mm width for a 4-pole frame is compact for the 100 A class — check the panel cutout and bus-bar spacing against those dimensions before committing. The optional motor drive (product extension) means it can be remotely operated, which is worth planning for if the panel spec calls for remote open/close.","metaTitle":"Siemens 3VA2110-7KQ42-0AA0 SENTRON 4P MCCB, 100 A, 330 kA","metaDescription":"Siemens SENTRON 3VA2110-7KQ42-0AA0 molded case circuit breaker, 4-pole, 100 A, ETU860 release, 330 kA at 240 V.
