What this MCCB delivers
The Siemens SENTRON 3VA2225-6JP32-0DA0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C through 50 °C, with a thermal derating curve that drops to 200 A at 70 °C. Breaking capacity reaches 242 kA at 240 V, 187 kA at 415 V and 440 V, and 121 kA at 500 V — at 690 V it holds 4.5 kA, so confirm the fault level on higher-voltage distribution. The unit includes an undervoltage release (UVR) and a communication function for integration into a monitored power system.
Panel fit and integration
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard SENTRON 3VA frame that mounts on a DIN rail or panel-mount adapter. The 3-pole footprint matches existing 3VA or older 3VL cutouts. Maximum power loss is 50.5 W, so factor that into enclosure thermal calculations. Operating range is -25 °C to 70 °C; storage from -40 °C to 80 °C.
