Product details

The Schneider Electric C25H34V160 is a 3-pole earth leakage circuit breaker from the ComPacT NSX250H frame, fitted with a MicroLogic 4.2 electronic trip unit rated 160 A at 40 °C.

Breaking capacity: the real-world fault interruption

The C25H34V160 carries an H breaking capacity code: 70 kA Icu at 380/415 V AC, 65 kA at 440 V, 50 kA at 500 V, and 35 kA at 525 V — all per IEC 60947-2. At 220/240 V it reaches 100 kA Icu. Under UL 60947-4-1 it delivers 65 kA at 480 V AC and 15 kA at 600 V AC. The 70 kA at 415 V is the common industrial service-entrance rating; the 50 kA at 500 V covers most 480 V North American panels. This is not a single-number breaker — the SCCR headroom varies by voltage, so the selectivity study should reference the voltage actually present at the fault point.

Frequently asked questions

What is the breaking capacity of C25H34V160 at 480V?

Under UL 60947-4-1, the C25H34V160 delivers 65 kA Icu at 480 V AC. Per IEC 60947-2, it delivers 50 kA Icu at 500 V AC and 35 kA at 525 V AC.

What protection functions does the MicroLogic 4.2 trip unit offer?

The MicroLogic 4.2 provides L (long-time overload), So (short-time short-circuit with fixed delay), I (instantaneous short-circuit), and R (earth-leakage) protection — four protection curves in one electronic trip unit.

What is the rated current of C25H34V160?

The trip unit is rated 160 A at 40 °C. The device short name is NSX250H, indicating the 250 A frame with H breaking capacity.
