The Schneider Electric C25H32M220 is a ComPacT NSX250H moulded-case circuit breaker (MCCB) with a 220 A MicroLogic 2.2 M electronic trip unit, configured for motor protection across three poles. The H breaking capacity code delivers 100 kA Icu at 240 V AC and 70 kA at 415 V AC, both certified to IEC 60947-2 — sufficient for high-fault industrial distribution where the upstream transformer can deliver that level of prospective short-circuit current.
Trip unit and protection curves
The MicroLogic 2.2 M provides L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous) protection, with motor tripping classes 5, 10, and 20 selectable. The 220 A rating at 65 °C means the breaker carries its full frame current without derating at that elevated ambient — critical for enclosed panels where internal temperature rise is a constraint.
Rated 100 kA Icu at 240 V AC, 70 kA at 415 V AC, 65 kA at 440 V, 50 kA at 500 V, 35 kA at 525 V, and 10 kA at 690 V — all per IEC 60947-2. Under UL 60947-4-1 the ratings are 85 kA at 240 V, 65 kA at 480 V, and 15 kA at 600 V.
Physical integration and environment
Measures 161 x 105 x 86 mm (H x W x D), mounts on a backplate in horizontal or vertical orientation, and carries IP40 protection (IK07 impact resistance).
