Schneider Electric M9F22103 C60SP 3A 1P
The Schneider Electric M9F22103 is a single-pole miniature circuit breaker from the C60SP series rated at 3 A. It provides branch circuit protection for residential and light commercial electrical installations. The unit mounts on a standard DIN rail and uses a toggle actuator for manual switching. Its thermal-magnetic trip mechanism responds to both overload and short-circuit conditions.
Screw-clamp terminals accept 18 to 8 AWG conductors
The breaker features screw-clamp terminal connections that accept solid or stranded wire from 18 AWG up to 8 AWG. This range simplifies wiring for typical branch circuits without requiring specialised lugs or ferrules. The toggle actuator gives a clear visual indication of the contact position during maintenance or fault finding. No additional accessories or software are bundled with the device.
UL 1077 supplementary protector
As a UL 1077 recognised supplementary protector the device is not a replacement for a listed branch-circuit breaker where the code requires one. Its maximum AC interrupting rating is 14 kA at 120/240 V AC and it is rated for 240/415 V AC and 60 V DC systems. Installers must verify that the available fault current at the point of installation does not exceed this rating.

Questions about this item
Will the screw-clamp terminals on the C60SP need re-torquing after installation?
Screw-clamp terminals on the C60SP accept 18 AWG to 8 AWG conductors; they are designed to maintain clamping force without routine re-torquing under normal vibration.
At what fault level does the 14 kA interrupting rating become the limiting factor?
The C60SP is rated to interrupt up to 14 kA at 120/240 V AC; any prospective short-circuit current above that value would exceed the device’s tested breaking capacity.
How much heat does the 3 A thermal-magnetic trip generate during continuous all-day operation?
At its rated 3 A the C60SP runs within its thermal design for 240/415 V AC circuits; the compact 3.19 × 0.71 × 2.83 in body dissipates heat through the DIN-rail mount without forced cooling.
