The Siemens SENTRON 3VA2225-5HN32-0JA0 is a 3-pole molded case circuit breaker rated for 250 A continuous current. It delivers 187 kA interrupting capacity at 240 V and 121 kA at 415/440 V, with a derated 75.6 kA at 500 V and 4.5 kA at 690 V — covering the full low-voltage distribution range from 240 V line-to-line up to 690 V phase-to-phase. The 250 A frame holds its full rating up to 50 °C ambient; above that, derate linearly to 213 A at 70 °C (the maximum operating temperature). Designed for line protection, this MCCB carries a shunt trip release (STL) for remote tripping — no undervoltage release, no ground-fault monitoring, and no auxiliary switch fitted on this variant. The basic switch core is order code 3VA2225-5HN32-0AA0.
