The C25N1TM200 is a 1-pole ComPacT NSX circuit breaker from the NSX250N frame, fitted with a TM-D thermal-magnetic trip unit rated 200 A at 40 °C. It protects distribution circuits against overload (thermal L) and short-circuit (magnetic I) per EN/IEC 60947-2. The toggle control and front connections make it a straightforward panel fit for a backplate mount.
Rated 90 kA Icu at 220/240 V AC, 50 kA at 380/415 V and 440 V, 36 kA at 500 V, 35 kA at 525 V, and 10 kA at 660/690 V AC. For a distribution panel fed from a transformer, the 50 kA at 415 V gives solid headroom for most industrial service entrances. The 10 kA at 690 V still covers downstream subfeeds in 690 V plant networks.
