The breaker carries three auxiliary switches (HQ) for remote status indication, plus an undervoltage release with leading NO contacts — the leading contact arrangement means the UVR signals its own state before the breaker opens, useful in safety circuits that need to confirm the release is reset before reclosure. ## Thermal derating — what the 25 A rating actually means in a warm panel At 55 °C it derates to 24.1 A, at 60 °C to 23.1 A, and at 70 °C to 21.25 A. Plan for the ambient inside the enclosure, not the control-room temperature. ## Integration — dimensions, auxiliary components, and panel fit These are the factory-matched accessories for this breaker variant — order them alongside if the panel build requires the UVR or auxiliary switch to be pre-installed.","metaTitle":"Siemens 3VA2125-7JP32-0FD0 SENTRON MCCB, 25A, 330kA at 240V","metaDescription":"Siemens SENTRON 3VA2125-7JP32-0FD0 molded case circuit breaker, 25A rated, ETU550 trip unit, 330kA at 240V, 242kA at 415V.
