Product details

Motor protection breaker with magnetic-only trip

The C25N3MA220 is a ComPacT NSX 250N frame circuit breaker from Schneider Electric, built specifically for motor protection. It carries a 220 A MA (magnetic-only) trip unit rated at 65 °C — no thermal element, so it responds only to short-circuit faults, leaving overload protection to a separate motor starter or thermal relay. That makes it the right choice for applications where you want the breaker to clear a fault fast without nuisance tripping on motor inrush.

Rated 90 kA Icu at 240 V AC and 50 kA at 415 V AC per IEC 60947-2, the N breaking capacity code (50 kA at 415 V) gives solid headroom for most industrial panel secondary feeds. The breaker is suitability-for-isolation certified, so it doubles as a visible disconnect in the motor branch circuit.

Integration notes

IP40 enclosure protection suits clean indoor panels; the IK07 impact rating handles routine panel access.

Frequently asked questions

What is C25N3MA220 used for?

It's a 3-pole motor protection circuit breaker with a magnetic-only (MA) trip unit rated 220 A. It provides short-circuit protection only; overload protection must be handled by a separate thermal relay or motor starter.

What is the breaking capacity of C25N3MA220?

90 kA Icu at 240 V AC, 50 kA at 415 V AC, 36 kA at 500 V AC, 35 kA at 525 V AC, and 10 kA at 690 V AC per IEC 60947-2. It also carries UL 60947-4-1 ratings: 85 kA at 240 V, 50 kA at 480 V, 15 kA at 600 V.
