Product details

The H breaking capacity code gives you 70 kA Icu at 415 V AC, which is the figure that governs most European 400 V industrial panels; at 240 V it rises to 100 kA, and at 690 V it drops to 10 kA. In a 40 °C panel you get a bit of headroom; in a hot enclosure above 50 °C you need to derate per the manufacturer's curve.

Mounting and integration into a panel

Mounts on a backplate — no DIN-rail clip here. The 4-pole body is 140 mm wide, 161 mm tall, 86 mm deep, with front-front connections (both line and load side). Rated for horizontal or vertical mounting flat on the backplate.

For a BOM line, the 250 A TM-D trip unit and H breaking capacity are the two specs that lock the fit. If your panel is designed around a 250 A NSX250H frame, this order code is the direct drop-in.

Frequently asked questions

What is the breaking capacity of C25H4TM250C at 415 V?

70 kA Icu at 380/415 V AC 50/60 Hz conforming to IEC 60947-2. That is the H breaking capacity code.

What is the closest alternative to C25H4TM250C in the same family?

Within the ComPacT NSX250H frame, the key variant is the trip unit type — this one is TM-D (thermal-magnetic). An electronic Micrologic trip unit in the same frame (e.g., NSX250H with Micrologic 2.3) would be the functional alternative if you need adjustable long-time, short-time, or ground-fault protection. Pin-compatible in the same panel cutout and busbar pattern.

Where can I buy C25H4TM250C?

Sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.

What compliance documentation does Schneider provide for C25H4TM250C?

The breaker is certified to EN/IEC 60947-2 and is suitable for isolation per that standard. IP40 and IK07 ratings are declared. Specific RoHS/REACH declarations are available from Schneider's product documentation portal for the ComPacT NSX series.
