This breaker carries its full 25 A rating from 40 °C up to 50 °C ambient, then derates linearly to 22.5 A at 70 °C — useful if the MCCB sits near transformers or drives inside a sealed enclosure. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep, so it fits standard SENTRON 3VA panel footprints and accepts the same busbar and accessory system.","metaTitle":"Siemens 3VA1125-6EF32-0AF0 SENTRON MCCB, 25 A, 3-Pole, 220 k","metaDescription":"Siemens 3VA1125-6EF32-0AF0 SENTRON molded case circuit breaker, 25 A rated continuous current, 3-pole, TM240 release, 220 kA at 240 V.
