At 415 V, the 242 kA rating means it can be placed upstream of a transformer or busway with very high available fault current — typical for large industrial switchboards — and still maintain selectivity with downstream devices. The 3-pole design and motor protection designation mean this MCCB is intended for three-phase motor branch circuits. Time-delay settings span 4 s minimum to 17 s maximum, which governs the short-time pickup and delay for coordination with downstream feeders. A 17 s delay at low overcurrents lets downstream breakers clear a fault first, maintaining selectivity. The maximum power loss is 37.5 W — relevant for thermal management inside a sealed enclosure. Dimensions are 110 mm depth, 138 mm width, and 248 mm height. This is a standard SENTRON 3VA2 form factor, designed for panel-mount or DIN-rail installation in a distribution board or motor control center. The 138 mm width fits a 3-pole MCCB footprint common across the 3VA2 family.","metaTitle":"Siemens 3VA2325-7MN32-0KA0 SENTRON MCCB, 250 A, 3-Pole, 330","metaDescription":"Siemens 3VA2325-7MN32-0KA0 SENTRON molded case circuit breaker, 250 A rated, 3-pole, 330 kA breaking capacity at 240 V.
