The 3-pole unit measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or panel-mount integration. The 220 kA at 240 V is the headline interrupting rating; at 500 V and 690 V it still holds 17 kA, which covers most motor-control and distribution applications at those voltages. The thermal derating is tight: the breaker holds 25 A from 40 °C through 50 °C, drops to 24 A at 55 °C and 60 °C, and to 23 A at 65 °C and 70 °C. ## Feature set and internal configuration This variant omits undervoltage release, voltage trip, ground-fault monitoring, and communication functions — it is a straight thermal-magnetic line-protection breaker. No trip indicator is fitted. For a panel where remote signaling or ground-fault detection is required, a different 3VA variant with those options would be needed.","metaTitle":"Siemens 3VA1125-6EF32-0AE0 SENTRON MCCB, 25 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1125-6EF32-0AE0 molded case circuit breaker, 25 A rated at 40 °C, 3-pole, 220 kA breaking capacity at 240 V.
