The Siemens SENTRON 3VA2225-6HL32-0AC0 is a 3-pole molded case circuit breaker rated for line protection, carrying a continuous current Iu of 250 A at 40 °C through 50 °C, then derating to 213 A at 70 °C. Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V and 440 V, dropping to 121 kA at 500 V and 6 kA at 690 V. It's a straight line-protection breaker: thermal-magnetic replacement with adjustable long-time, short-time, and instantaneous pickups.
Integration and mounting — fits a standard MCCB footprint
The 105 mm width is three-pole standard for this class — it occupies the same DIN-rail or panel-mount slot as other 250 A frame MCCBs. The IP40 front protection means the breaker face is sealed against tools and fingers but not washdown; install it in a dead-front enclosure or behind a gland plate. The basic switch variant (3VA2225-6HL32-0AA0) is the underlying mechanism; this order code adds the aux switches at the factory.
