The interrupting capacity reaches 330 kA at 240 V and 242 kA at 415 V, dropping to 7.5 kA at 690 V — the high short-circuit ratings at common low-voltage levels mean this breaker can be applied upstream in high-fault-capacity installations without cascading coordination issues. The 330 kA interrupting rating at 240 V is the headline number, but the more relevant figure for a 400 V three-phase system is 242 kA at 415 V, still well above typical industrial service-entrance fault levels. At 690 V the capacity drops to 7.5 kA, so this breaker is not intended for 690 V motor circuits unless the available fault current is verified below that threshold. The 20 000-cycle latching endurance reflects a robust mechanism for frequent switching applications, though it is not a full-load switching rating — that is the contactor's job. ## Integration and auxiliary features The 138 mm width and 248 mm height fit standard SENTRON 3VA2 panel cutouts; the 110 mm depth leaves clearance for rear-connected busbars. Maximum power loss is 38 W, which should be factored into enclosure thermal calculations when multiple breakers are ganged.","metaTitle":"Siemens 3VA2325-7MN32-0CB0 SENTRON MCCB, 250 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2325-7MN32-0CB0 SENTRON molded case circuit breaker, 250 A rated continuous, 3-pole motor protection version, 330 kA at 240 V.
