The interrupting ratings are substantial: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V — so it can be applied in high-fault-capacity main or feeder positions where SCCR coordination matters. This unit includes a factory-installed shunt trip (STL) auxiliary release, meaning it can be remotely tripped via a control voltage for emergency stop or load-shedding schemes. The insulation voltage is rated 800 V, and the breaker measures 140 mm wide by 158 mm tall by 70 mm deep — a standard 4-pole MCCB footprint that fits SENTRON panelboard and switchboard mounting patterns.
Above that, derating is linear: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C.
