Product details

The magnetic trip responds only to short-circuit currents — no thermal overload curve — so you pair it with a separate motor starter or overload relay upstream. The H breaking capacity code means it delivers 70 kA Icu at 415 V AC per IEC 60947-2, with a full ladder of ratings from 100 kA at 240 V down to 10 kA at 690 V AC. That SCCR headroom lets it sit confidently in high-fault distribution, not just branch motor circuits.

At 161 x 105 x 86 mm (H x W x D), it takes up a standard 3-pole breaker footprint. The IP40 enclosure keeps dust out of the control cabinet; IK07 impact rating handles accidental tool bumps during maintenance.

The 100 A MA trip unit is magnetic-only — it sees short-circuit faults, not overloads. That's intentional for motor protection: the overload relay handles the running current, and the breaker clears the high fault.

Frequently asked questions

Where can I buy C16H3MA100 and get a price?

We source the C16H3MA100 to order against an RFQ. Availability and current pricing are confirmed at quote time — send us your request and we'll respond with a commercial offer.

What is the closest alternative to C16H3MA100 in the ComPacT NSX family?

The C16H3MA100 is the 100 A MA-trip variant of the NSX160H frame. The closest sibling would be the same frame with a different trip rating or a TM (thermal-magnetic) trip unit if you need combined overload and short-circuit protection in one device — but the MA trip is specifically for motor circuits where overload protection is handled externally.

What compliance documentation does Schneider provide for C16H3MA100?

The breaker is designed to EN/IEC 60947-2 and carries suitability for isolation per that standard. UL 60947-4-1 ratings are also listed for the breaking capacity at 240 V, 480 V, and 600 V AC. RoHS and REACH compliance are standard for current-production Schneider molded-case breakers.
