This breaker delivers 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. Those are the maximum interrupting ratings at each voltage level — the actual available fault current at your panel's secondary must fall below these to maintain coordination. No rewiring needed if you're swapping from a sibling with the same pole count and frame — the mounting footprint and terminal spacing are identical. ## Trip unit and thermal performance Maximum power loss is 7.7 W, which is modest for a 100 A frame and keeps internal cabinet heating manageable.","metaTitle":"Siemens 3VA2010-8KP42-0AA0 SENTRON MCCB, 100 A, 4-Pole, ETU8","metaDescription":"Siemens SENTRON 3VA2010-8KP42-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, ETU850 electronic trip unit.
