Product details

It delivers a breaking capacity of 100 kA Icu at 240 V AC 50/60 Hz per IEC 60947-2, dropping to 70 kA at 415 V and 35 kA at 690 V — a curve that covers most distribution and motor branch circuits in North American and European panels. The H-frame (NSX160H) means this breaker is sized for 160 A frame but fitted with a 100 A trip, giving headroom for future load growth without swapping the entire device.

At 480 V AC the C16H4TM100 is rated 65 kA Icu per UL 60947-4-1, which is the typical service-entrance or main-tie SCCR in a 480 V industrial panel. The TM-D trip provides fixed thermal (L) and fixed magnetic (I) protection — no interchangeable rating plugs, so what you order (100 A) is what protects the circuit.

Front-front connections (both line and load) simplify bus-bar routing in a panel — no need to reach behind the breaker. 140 mm wide, 161 mm high, 86 mm deep, with a 35 mm connection pitch that matches standard bus-bar spacing.

Rated for 40,000 mechanical cycles and 20,000 electrical cycles at rated current (440 V In). That is a solid service life for a main or feeder breaker in a panel that sees a few operations per day.

Frequently asked questions

Where can I buy C16H4TM100 and how do I get a price?

The C16H4TM100 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 C16H4TM100's breaking capacity at 415 V?

At 415 V AC 50/60 Hz per IEC 60947-2, the C16H4TM100 delivers 70 kA Icu. This is the standard H-frame breaking capacity for the ComPacT NSX160H at typical European distribution voltage.

What compliance documentation does Schneider provide for C16H4TM100?

The C16H4TM100 is certified to EN/IEC 60947-2 and UL 60947-4-1. It carries IP40 per IEC 60529 and IK07 per IEC 62262. Pollution degree 3 per IEC 60664-1. Standard Schneider documentation includes the declaration of conformity and test certificates for the listed standards.
