The Siemens 3VA2225-6HN42-0BH0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A maximum continuous current, with a 4-pole configuration and an interrupting capacity of 242 kA at 240 V. That interrupting rating drops to 187 kA at 415 V and 440 V, then to 121 kA at 500 V, and to 4.5 kA at 690 V — so the available fault current at your service voltage determines whether this frame is adequate.
At 55 °C it derates to 241 A, at 60 °C to 232 A, at 65 °C to 222 A, and at 70 °C to 213 A.
The 140 mm width across four poles is the key panel-space constraint — standard for a 4-pole MCCB in this frame size. The 86 mm depth fits most distribution board enclosures without gland-plate interference.
