The interrupting capacity reaches 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at both 500 VAC and 690 VAC — numbers that govern selectivity coordination in high-fault panels. ## Integration — panel footprint and auxiliary wiring The breaker occupies 76.2 mm width (3 in), 130 mm height (5.12 in), and 70 mm depth (2.76 in) — a standard SENTRON 3VA frame size that fits existing DIN-rail or panel-mount cutouts for this series. Maximum power loss is 25 W, which factors into enclosure thermal calculations. ## Configuration — base switch variant and release options The design is line protection — not suited for motor circuit protection without additional overload relay. The two auxiliary switches (HQ) provide status signaling for the open/closed position.","metaTitle":"Siemens 3VA1110-4EF32-0HC0 SENTRON MCCB, 100A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1110-4EF32-0HC0 molded case circuit breaker, 100A rated, 3-pole, 121 kA breaking capacity at 240 VAC.
