Its interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V, and 121 kA at 500 V — numbers that tell you it's built for high-fault main feeders, not branch circuits. The 110 mm depth, 138 mm width, and 248 mm height fit standard SENTRON panel footprints; the auxiliary switch complement (2 aux + 1 trip alarm + 1 electrical alarm) and integrated shunt trip (STL) cover remote signaling and emergency trip without an external module.
The 630 A rating at 40 °C is the headline number, but the derating curve matters for a crowded panel: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. Maximum power loss is 162 W — that's heat that has to leave the enclosure. If your ambient hits 50 °C, you're down to 593 A continuous; plan the fill factor and ventilation accordingly.
Integration and approvals
The 3-pole design with a trip indicator and voltage trigger simplifies troubleshooting — when the breaker trips, you see it without poking at the load side.
