Its interrupting capacity hits 242 kA at 240 V and still holds 187 kA at 415 V — that's serious fault-clearing headroom for a 250 A frame. The 105 mm width and 181 mm height fit standard panel layouts; depth runs 86 mm.
At 500 V it still delivers 121 kA; at 690 V it drops to 4.5 kA, so it's not a 690 V main breaker but handles downstream feeders at that voltage. Thermal derating is gradual: 250 A holds steady through 50 °C, then drops to 241 A at 55 °C and 213 A at 70 °C. That means in a hot panel (say 55 °C ambient), you lose only 9 A — still well within a 250 A load's margin.
Built-in accessories and fit
That saves panel-builder wiring time — no separate add-on modules to snap in. The base switch is order code 3VA2225-6HL32-0AA0; the -0JH0 suffix adds the shunt trip and aux switches.
