Schneider Electric M9F22108 Miniature Circuit
This single-pole breaker provides branch circuit protection for AC systems up to 240/415V and DC systems up to 60V. It is suited for installers and panel builders who need a compact device rated at 8A with a thermal-magnetic trip curve C.
DIN-rail mounting frees panel space
The unit clips onto standard DIN rail and uses screw-clamp terminals that accept conductors from 18 AWG up to 8 AWG. Its 14kA interrupting rating at 120/240V AC handles fault currents without requiring additional upstream coordination in many supplementary protector applications.
Toggle actuator gives clear on/off indication
The front-mounted switch shows status at a glance and allows immediate restoration after a trip. UL 1077 listing confirms compliance for supplementary protection, while the C60SP series dimensions of 3.19 in length, 0.71 in width and 2.83 in depth fit tight enclosures.

Questions about this item
Will the 14 kA interrupting rating hold up on a 240 V circuit that runs continuously?
The supplementary protector is rated 14 kA at 120/240 V AC, so it can clear a fault at that level on a 240 V branch circuit.
Does the thermal-magnetic trip generate noticeable heat or noise during all-day operation on an 8 A load?
The device uses a thermal-magnetic trip with a toggle actuator; it runs silently and its 0.71 in width allows normal DIN-rail spacing for heat dissipation.
What wire gauges and mounting hardware do I need to install this single-pole breaker?
Accepts 18 to 8 AWG conductors via screw-clamp terminals and mounts on standard DIN rail using the integral clip.
