Product details

The Schneider Electric C40H44V400 is a ComPacT NSX400H molded case circuit breaker rated 400 A at 40 °C, 4-pole, with an integrated MicroLogic 4.3 electronic trip unit. Backplate-mounted, toggle-operated, front-connected.

The MicroLogic 4.3 trip unit combines L (long-time overload), So (short-time short-circuit with fixed delay), I (instantaneous short-circuit), and R (earth-leakage) protection in one package. The earth-leakage is integrated, not a separate module — saves a slot in the panel.

Lifecycle status is current production. No end-of-life notification or successor order code is known.

IP40 enclosure rating (IK07 impact) suits clean indoor panel environments — not rated for washdown. Electrical durability: 12,000 cycles at 440 V at half-rated current, 6,000 cycles at full rated current. Mechanical durability: 15,000 cycles.

Frequently asked questions

What is the breaking capacity of C40H44V400 at 415 V?

70 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. At 440 V it drops to 65 kA Icu; at 480 V UL rating it holds 65 kA Icu.

What protection functions does the MicroLogic 4.3 trip unit provide?

L (long-time overload), So (short-time short-circuit with fixed delay), I (instantaneous short-circuit), and R (earth-leakage protection). All four are integrated into the trip unit.

What compliance documentation is available for C40H44V400?

The breaker is certified to EN/IEC 60947-2 and UL 60947-4-1. Pollution degree 3 per IEC 60664-1. IP40 per IEC 60529, IK07 per IEC 62262.
