Eaton FAZ-C1/1-SP 1A Circuit Breaker
The Eaton FAZ-C1/1-SP is a single-pole miniature circuit breaker rated at 1 A with a C-curve characteristic. It provides supplementary protection for control circuits and low-current equipment in industrial panels. The device mounts on a standard DIN rail and complies with UL 1077 for recognised component use.
DIN Rail Mounting and Panel Integration
The 17.7 mm module width per pole keeps the unit compact inside crowded enclosures. Standard terminals accept wiring without special tools and captive screws prevent lost hardware during installation. A contact position indicator shows the toggle state at a glance while finger-proof terminals improve safety during maintenance. Snap-on accessories allow future expansion without rewiring the base unit.
Thermal-Magnetic Trip Under Sustained Load
The thermal-magnetic mechanism responds to prolonged overcurrents with a delayed trip and to short circuits with a fast magnetic trip. Current-limiting action reduces let-through energy during fault conditions. The trip-free mechanism prevents the contacts from being held closed against a fault even if the toggle is forced. Rated for 277/480 VAC, the breaker is suitable for supplementary protection up to 63 A in the series.

Questions about this item
What current limit triggers the thermal-magnetic trip on the FAZ-C1/1-SP under sustained overload?
The C-curve characteristic trips magnetically between 5 A and 10 A and thermally above the 1 A rating during sustained overload.
How much heat does the 17.7 mm wide module dissipate when carrying 1 A continuously all day?
Power loss at rated current is low for supplementary protection; the current-limiting design and finger-proof terminals keep temperature rise within UL 1077 limits.
Which DIN rail profile and upstream breaker rating are required to install this supplementary protector?
It snaps onto standard 35 mm DIN rail and must be backed by a branch-circuit breaker rated no higher than 63 A per UL 1077.
