That is unusual for an MCCB and simplifies panel design in hot enclosures or near other heat sources. Four poles handle three-phase plus neutral switching. The interrupting ratings are tiered by system voltage: 187 kA at 240 VAC, 121 kA at 415/440 VAC, 75.6 kA at 500 VAC, and 7.5 kA at 690 VAC. Dimensions are 110 mm deep, 184 mm wide, 248 mm tall. Power loss is 37.5 W maximum at rated current.","metaTitle":"Siemens 3VA2325-5HK42-0AB0 SENTRON MCCB, 250 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2325-5HK42-0AB0 molded case circuit breaker, 250 A continuous, 4-pole, 187 kA breaking capacity at 240 VAC.
