Breaking capacity of 121 kA at 415 V (and 187 kA at 240 V) means this breaker can safely interrupt very high fault currents typical of large transformer-fed installations; the 7.5 kA at 690 V still covers most 690 V motor circuits. Three-pole design with undervoltage release and phase failure detection — the UVR drops the breaker on loss of control voltage, and the phase-failure circuit trips on single-phasing, both standard for motor protection duty. ## Physical integration — panel and DIN considerations Dimensions 248 mm high × 138 mm wide × 110 mm deep; the 138 mm width (5.43 in) is standard for a 3-pole MCCB in this class, so it fits existing SENTRON 3VA2 panel cutouts and busbar systems without re-spacing. ## Auxiliaries and releases — what ships on the breaker Factory-fitted with two HQ auxiliary switches and an undervoltage release (UVR) — the UVR is the 3VA2325-5MN32-0AA0 basic switch variant. Trip indicator is absent. ## Environmental limits and power loss Maximum power dissipation 40 W at rated load — factor this into enclosure cooling calculations.","metaTitle":"Siemens 3VA2325-5MN32-0BC0 SENTRON MCCB, 250A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA2325-5MN32-0BC0 molded case circuit breaker, 250 A, 3-pole, 121 kA breaking capacity at 415 V.
