ComPacT NSX630H with MicroLogic 7.3 E — 570 A, 100 kA
The Schneider Electric C63H37E570 is a ComPacT NSX630H molded-case circuit breaker with a MicroLogic 7.3 E electronic trip unit, rated 570 A at 40 °C. It delivers 100 kA Icu at 240 V AC (IEC 60947-2) and 85 kA Icu at 240 V AC (UL 60947-4-1), making it a high-interrupting-capacity choice for distribution and motor-circuit protection in industrial panels.
Breaking capacity and protection
Breaking capacity steps down with voltage: 70 kA at 415 V, 65 kA at 440 V, 50 kA at 500 V, 35 kA at 525 V, 20 kA at 690 V AC — all per IEC 60947-2. Under UL 60947-4-1, it holds 65 kA at 480 V and 20 kA at 600 V AC. The MicroLogic 7.3 E provides L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and R (earth-leakage) protection, with an LCD display for metering and event logs.
Front connections (upside and downside) simplify bus-bar routing in switchgear. Rated for pollution degree 3 (IEC 60664-1) and overvoltage category IV, with an IK07 impact rating. Operates at 0–2000 m altitude without derating; derate above 2000 m. Ambient humidity range 0–95 %.
