In a sealed enclosure or high-ambient switchroom, that derating curve determines whether the breaker can carry the design load without nuisance tripping. The 86 mm depth, 140 mm width, and 181 mm height place it in the standard SENTRON 3VA2 footprint — it bolts directly onto the mounting plate or busbar adapter used across the 3VA2 family, so a panel kitted for a sibling variant accepts this unit without drilling or rework.","metaTitle":"Siemens 3VA2225-5HN42-0CA0 SENTRON MCCB, 250 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5HN42-0CA0 molded case circuit breaker, 250 A continuous, 4-pole, 187 kA breaking at 240 V.
