The Schneider Electric C063H32AFM is a ComPacT NS new generation moulded-case circuit breaker, rated 630 A at 50 °C with a MicroLogic 2.0 A electronic trip unit. It's a 3-pole, manually operated unit built for distribution duty in fixed-mount, backplate installations.
Trip unit and protection logic
The MicroLogic 2.0 A provides L (long-time overload) and I (instantaneous short-circuit) protection curves. This is an electronic trip unit, so you get adjustable thermal memory (20 mn) that keeps the breaker from nuisance-tripping on repeated inrush — a real help when starting motor loads or feeding transformers that hit the thermal curve on re-close. The LCD display and ammeter function let you read load current directly on the face, which saves a clamp-meter walk for troubleshooting.
Physical fit in the panel
Fixed-mount on a backplate, front connections both top and bottom. The 210 mm width, 327 mm height, and 147 mm depth are the numbers to check against your enclosure's gland-plate area and bus-bar takeoff pitch (70 mm between poles). IK07 impact rating means it takes a knock from a dropped tool without cracking the LCD.
