That matters when you're coordinating downstream feeders — you can shape the trip curve to ride through motor inrush and still catch a hard fault fast. That simplifies the BOM and the panel wiring: one line item covers the breaker and its shunt-trip function for safety circuits. ## Integration into the panel — dimensions and mounting It's a fixed-mount design — no draw-out cradle — so plan for bolted bus connections in the distribution section. The depth leaves room for rear cable access in a 400 mm deep enclosure. The interrupting curve is steep: 187 kA at 240 V, 121 kA at 415 V, 79 kA at 500 V, and 5.1 kA at 690 V. That tells you the arc extinction relies on voltage-dependent chamber design — at 690 V you need upstream current-limiting fuses or a higher-rated breaker if the available fault current exceeds 5.1 kA. For typical 480 V distribution in North America, 79 kA covers most industrial service entrances. For a line-up MCCB that gets cycled maybe a few times a year for maintenance isolation, that's effectively unlimited. The trip indicator is not fitted on this variant, so you'll need the auxiliary contacts or a visual check to confirm tripped status.","metaTitle":"Siemens 3VA2225-5HN42-0DC0 SENTRON MCCB, 250 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2225-5HN42-0DC0 molded case circuit breaker, 250 A rated, 187 kA interrupting at 240 V.
