Breaking capacity hits 121 kA at 240 V and 75.6 kA at 415 V, so it handles high-fault utility feeds without cascading upstream. The breaker measures 70 mm deep, 50.8 mm wide (2 inches), and 130 mm tall. Two inches per pole means a 2-pole unit occupies roughly 4 inches of DIN-rail width — standard for the SENTRON 3VA family. Maximum power loss is 16.66 W, which contributes to the enclosure thermal budget.","metaTitle":"Siemens 3VA1110-4ED26-0AA0 SENTRON MCCB, 100 A, 2-Pole, 121","metaDescription":"Siemens SENTRON 3VA1110-4ED26-0AA0 molded case circuit breaker, 100 A rated, 2-pole, 121 kA breaking at 240 V.
