The Siemens SENTRON 3VA2225-5JQ32-0HH0 is a 3-pole molded case circuit breaker rated 250 A continuous at 40 °C, with a maximum interrupting capacity of 187 kA at 240 V AC. At 415 V it still holds 121 kA, and at 690 V it drops to 4.5 kA, so the voltage class of your distribution determines where this breaker lands. Rated current holds flat at 250 A from 40 °C through 50 °C, then derates to 200 A at 70 °C. That thermal curve means you size the breaker for the ambient inside the enclosure, not the room temperature — a panel running at 55 °C knocks the rating to 238 A.
Fit and integration
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard SENTRON 3VA footprint that drops into the same DIN-rail or screw-mount panel cutout as other 3VA2 frame breakers. The depth of 86 mm leaves room for rear busbar connections in a typical 200 mm deep enclosure.
The lifecycle stage is listed as current, meaning this is an active catalog item in the SENTRON line.
