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.","metaTitle":"C25N3MA220 ComPacT NSX 250N 3P 220A Magnetic Trip Motor Circ","metaDescription":"C25N3MA220 ComPacT NSX 250N 3-pole 220A circuit breaker with MA magnetic trip unit for motor protection. 90 kA breaking capacity at 240 V AC.
