The Siemens 3VA2225-6JQ32-0AC0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 250 A through 50 °C with no derating — at 55 °C it still holds 238 A, and at 70 °C it delivers 200 A. That thermal curve means this breaker handles a 250 A bus in a warm panel without stepping down to a smaller frame. Three poles, 800 V rated insulation voltage, and a 48 W max power loss. The interrupting ratings climb to 242 kA at 240 V and 187 kA at 415 V and 440 V, then drop to 121 kA at 500 V and 6 kA at 690 V — that 690 V figure is the weak point; if your system runs at 690 V, this frame is not your high-fault pick. The auxiliary contact version is two HQ auxiliary switches. Communication function is present — this breaker talks to a BMS or PLC for remote monitoring and trip events.
Same 250 A frame, same ETU560 trip unit, same 3-pole layout. Both share the 105 x 181 x 86 mm envelope.
