At 690 V it still holds 52.5 kA, so it handles industrial 480Y/277 V or 600 V systems without derating the interrupting rating. That's unusual for a thermal-magnetic MCCB at this frame size; most lose 10–15 % above 50 °C.
Integration and mounting — what fits
Bolts onto the backplate or mounts on a mounting plate; no DIN-rail clip on this frame size. The 4-pole body takes the same panel cutout as the 3-pole variant, just wider. Verify busbar spacing if retrofitting into an existing 3-pole-only panel.
Ground-fault and communication — what's built in
The breaker includes a ground-fault monitoring function using summation current formation on L + N conductors — it measures vector sum of phase and neutral currents to detect leakage to ground. No external GF relay needed for that function. Communication function is onboard, so it can report status or trip events to a BMS or PLC without an add-on module.
