It's a 3-pole, 630 A frame with a MicroLogic 5.0 electronic trip unit providing LSI protection — long-time overload, short-time short-circuit, and instantaneous short-circuit.
If your enclosure runs hotter, you'll need to consult the thermal derating curve — but for most industrial switchboards, 630 A covers a large motor control center feeder or a transformer secondary. The MicroLogic 5.0 is electronic, so it gives you adjustable long-time, short-time, and instantaneous pickup settings, plus a 20-minute thermal memory that prevents nuisance tripping on repeated overloads. The IP40 front face and IK07 impact resistance are adequate for enclosed panel mounting; it's not rated for washdown environments.
Fixed mount on a backplate — no draw-out cradle. The 210 mm width, 327 mm height, and 147 mm depth fit standard switchboard cubicle compartments. The manually operated control type means no motor operator or shunt trip is included; those are add-on accessories. Four red LEDs for fault indication and one yellow for overload give local status without opening the door.
