At 415 V the capacity is still 75.6 kA, and at 690 V it drops to 11.9 kA, so the voltage you're clearing at governs the SCCR you can count on for coordination studies. The 3-pole construction and 800 V rated insulation voltage (Ui) suit it for 480Y/277 V and 600 V delta systems common in North American and European industrial panels. Derating is minimal up to 50 °C — the breaker holds 25 A flat from 40 °C to 50 °C, then drops to 24 A at 55 °C and 22.5 A at 70 °C.
Deployment context — panel integration
This MCCB is a panel-mount device, not DIN-rail snap-on. The 76.2 mm width (roughly 3 inches) and 130 mm height fit standard MCCB cutouts in industrial enclosures. Depth is 70 mm, which leaves clearance for rear-mounted bus bars or wiring ducts. The auxiliary contact version is listed as 2 auxiliary switches HQ. HQ typically denotes high-rupturing-capacity contacts rated for switching control circuits directly without intermediate relays — useful for direct PLC inputs or contactor coils in the same panel.
