Product details

The C10H3TM100C is a Schneider Electric ComPacT NSX100H molded-case circuit breaker with a 100 A TM-D thermal-magnetic trip unit, 3 poles, and an H breaking capacity code delivering 70 kA Icu at 415 V AC. The TM-D trip provides fixed thermal (overload) and fixed magnetic (short-circuit) protection curves, so it's a straight swap-in for a BOM that calls for a non-adjustable trip. Rated 100 A at 50 °C, meaning no derating at typical panel ambient; above that, the thermal curve shifts.

Deployment context

Mounts on a backplate in a distribution panel — horizontal or vertical, flat against the mounting surface. Front connection both line and load sides, with a 35 mm connection pitch that matches standard busbar systems. The 105 mm wide × 161 mm high × 86 mm deep footprint fits standard MCCB cutouts. Five accessory slots allow adding shunt trips, auxiliary contacts, or motor operators without removing the breaker from the panel.

Suitability for isolation per that standard — meaning it can be used as a visible-break disconnecting means. Electrical endurance of 50,000 cycles at 440 V In/2 and 30,000 cycles at full rated current — this is a distribution breaker, not a switching device for frequent motor starts.

Frequently asked questions

Where can I buy C10H3TM100C and how do I get a price?

The C10H3TM100C is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is C10H3TM100C's breaking capacity at 415 V?

The C10H3TM100C delivers 70 kA Icu at 380/415 V AC 50/60 Hz conforming to IEC 60947-2. This is the H breaking capacity code, suitable for high-fault industrial mains.

What compliance documentation does Schneider provide for C10H3TM100C?

The C10H3TM100C is certified to EN/IEC 60947-2 and is suitable for isolation per that standard. It carries an IP40 protection degree (IEC 60529) and IK07 mechanical impact rating (IEC 62262). Pollution degree 3 and overvoltage category III per IEC 60664-1.
