Schneider Electric C10N1TM040 ComPacT NSX100N 1P 40 A 25 kA at 240 V TM-D Fixed Moulded Case Circuit Breaker
Schneider Electric C10N1TM040 - ComPacT NSX100N 1P 40 A 25 kA TM-D moulded case circuit breaker.
Description
About the NSX100N
About the NSX100N
The Schneider Electric C10N1TM040 is a 1P, 40 A ComPacT NSX100N moulded case circuit breaker fitted with a TM-D thermal-magnetic trip unit rated for 25 kA breaking capacity at 240 V AC. It carries a 277 V rated operational voltage and mounts on a fixed backplate, suited to distribution circuits sized to its 40 A nameplate rating.
Certifications & Standards
- EN/IEC 60947-2
Selection Notes
The N frame sits at the mid tier of the ComPacT NSX100 breaking-capacity ladder (25 kA at 240 V AC), between the F (36 kA) and H (70 kA) frames of the same ComPacT NSX100 footprint. The TM-D trip unit on this C10N1TM040 variant has its thermal pickup fixed at 1x In, so the 40 A rating is the circuit's protected current with no field adjustment; choose the adjacent current rating in the same N frame if the protected load differs from 40 A.
