What this 250 A SENTRON MCCB carries
The Siemens 3VA2225-6JQ32-0KL0 is a SENTRON molded case circuit breaker on a 250 A frame, 3-pole, designed for line protection in distribution panels. Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V, which covers most industrial service-entrance and feeder applications where high fault current is expected. At 690 V the rating drops to 4.5 kA — that's the limit for a 690 V bus; if your panel runs that voltage, verify the available fault current stays under that number. The breaker carries a full 250 A up to 50 °C ambient; at 55 °C it's 238 A, at 60 °C it's 225 A, and at 70 °C it's 200 A. Communication function is built in, which means it can report status and trip events to a BMS or PLC without an add-on module. The basic switch variant is 3VA2225-6JQ32-0AA0 — the -0KL0 suffix adds the communication and alarm package.
Footprint is 105 mm wide by 181 mm tall by 86 mm deep — a standard 3-pole MCCB form factor that drops into most SENTRON or third-party distribution panels without re-drilling. The 86 mm depth (3.39 in) is shallow enough for 200 mm deep enclosures; check your panel's internal clearance if you're retrofitting into an existing bucket.
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
