The Siemens SENTRON 3VA2225-6HL32-0HC0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C, with a thermal derating curve that holds 250 A through 50 °C, then drops to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. The interrupting ratings are the key selection parameter: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V. If your fault current at 690 V exceeds 4.5 kA, this is not the right frame. The 86 mm depth, 105 mm width, and 181 mm height place it in the standard 3VA2 frame footprint. It mounts directly into a SENTRON panelboard or distribution board without adapters. The design is line protection, not feeder or motor protection — the trip unit is configured for cable and busbar protection, not overload curves for motor starting.
Built-in accessories and wiring
The basic switch is order code 3VA2225-6HL32-0AA0 — that's the core breaker without the auxiliaries; this -0HC0 suffix adds the STL and HQ switches factory-installed. If you need UVR or ground-fault, this is not the variant; you'd step to a different suffix.
