The 25 A rating holds across 40 °C to 50 °C ambient (no derating needed up to that point), then steps down to 24 A at 55–60 °C and 23 A at 65–70 °C. Interrupting ratings at each voltage level are: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V panel the relevant figure is 32 kA; for a 600 V class system you use the 11.9 kA at 690 V. It is a basic line-protection MCCB — no remote trip or status feedback built in. Maximum power loss is 8.5 W, which contributes to the enclosure thermal budget. Dimensions are 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in). The 3-pole footprint matches standard SENTRON 3VA panel layouts. The supplied basic switch variant is 3VA11253EF320AA0. The breaker has no trip indicator and no voltage trigger. No official successor has been issued; the 3VA1125-3EF32-0AB0 is the current production variant for this rating and release combination.","metaTitle":"Siemens 3VA1125-3EF32-0AB0 SENTRON MCCB, 25A, 75.6kA at 240V","metaDescription":"Siemens SENTRON 3VA1125-3EF32-0AB0 molded case circuit breaker, 25 A rated, 3-pole, TM240 release.
