For a 415 V distribution board, the 75.6 kA rating gives good headroom above typical 50 kA prospective fault levels, supporting selective coordination with downstream 25-50 kA rated MCBs. ## Thermal derating and continuous current Above that, derating is gradual: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. In a crowded panel with internal temperature rise, plan for the derated figure at the actual ambient. Maximum power loss is 25 W at rated current — heat dissipation that must be factored into enclosure thermal calculations.","metaTitle":"Siemens 3VA1110-4EF42-0AA0 SENTRON MCCB, 100 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1110-4EF42-0AA0 SENTRON molded case circuit breaker, 100 A at 40 °C, 4-pole, TM240 release, breaking capacity 121 kA at 240 V.
