Breaking capacity hits 220 kA at 240 V, drops to 154 kA at 415 V, and still holds 75.6 kA at 440 V. That's serious fault-interruption headroom for a 125 A frame.
Panel footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — standard MCCB spacing for a 125 A frame. The auxiliary contact version ships with 2 auxiliary switches (HQ type), and an undervoltage release is built in.
Above that it starts to step down: 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, 112.5 A at 70 °C.
