Breaking capacity hits 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V; the 440 kA at 240 V figure covers high-fault industrial services where the upstream transformer can deliver extreme short-circuit current. The ETU330 electronic overcurrent release handles line protection with adjustable N-conductor protection (OFF, 50%, 100%) and adjustable response times (tr min 0.5 s, max 17 s). Ground-fault monitoring is built in via summation current formation on L + N, so this breaker can serve as the main disconnect in a grounded-wye distribution panel without an external GF relay. ## Panel fit and lifecycle Dimensions are 86 mm deep, 140 mm wide, 181 mm high — a 4-pole frame that fits standard SENTRON 3VA mounting footprints. ## Coordination and selectivity The 20000 latching-endurance cycles support frequent switching in motor-starting or capacitor-bank applications where the breaker doubles as a disconnect. Maximum power loss of 7.7 W keeps internal cabinet temperature rise manageable — relevant when multiple breakers are ganged in a row.","metaTitle":"Siemens 3VA2110-8HM46-0AA0 4-Pole MCCB, 100 A, 440 kA at 240","metaDescription":"Siemens SENTRON 3VA2110-8HM46-0AA0 molded case circuit breaker, 4-pole, 100 A rated, 440 kA at 240 V.
