Overview
The C63F37E570 is a Schneider ComPacT NSX molded case circuit breaker rated 570 A at 40 °C with a 40 kA interrupting capacity at 440 V AC, 60 Hz, in a 3-pole fixed-mount frame. It carries the MicroLogic 7.3 E electronic trip unit, which combines LSI protection curves with earth-leakage (R function) and onboard energy metering with time-stamped event logs.
How it compares
Compared to the 4-pole C63H4 (630 A, 85 kA at 690 V AC), the C63F37E570 is a 3-pole 570 A frame with a 40 kA IC at 440 V AC — pick the C63H4 when the BOM requires a fourth pole, a higher 630 A continuous rating, or a full 85 kA IC on a 690 V line.
Integration
The MicroLogic 7.3 E trip unit occupies all six slots of the breaker cradle and provides L, S, I, and R protection plus energy metering via the front LCD display. The 45 mm terminal pitch and fixed-mount chassis match standard ComPacT NSX panel cutouts.
