Circuit Breaker · 5A 1-Pole 277V C-Curve 10 kAIC DIN Rail Mount · Eaton FAZ-C5/1-NASP
SKU: EAT-FAZ-C5/1-NA-SP
5A single-pole DIN rail miniature circuit breaker for 277V control and branch protection applications. C-curve tripping is commonly used where moderate inrush is expected, such as small transformers and pilot devices; verify coordination, voltage, and interrupt rating for the installation.
What this product is for
This Eaton FAZ-C5/1-NA-SP is a 5A single-pole DIN rail miniature circuit breaker used for branch and supplementary protection in commercial and industrial control panels. It is rated 277V, 50-60 Hz, with a 10 kAIC interrupt rating and C-curve tripping for applications with moderate inrush current.
Use for
Use for DIN rail panelboards, industrial control panels, small transformers, pilot devices, and other circuits where a 5A breaker with C-curve characteristics is required. Screw terminals support standard panel wiring practices.
Avoid for
Avoid using this breaker where a different trip curve, pole count, voltage rating, or interrupt rating is required. Do not substitute it without confirming code compliance, equipment listing, and panel compatibility.
Best for
Best for electricians and panel builders needing a compact 1-pole breaker for North American DIN rail systems where moderate startup inrush is expected. Typical guidance: C-curve breakers are commonly selected for circuits with higher inrush than resistive loads, but actual suitability depends on the connected equipment and coordination study.
Installed in
Installed in commercial and industrial enclosures, OEM panels, machinery control cabinets, and distribution assemblies using DIN rail mounting. Product dimensions are approximately 4.13 in H x 2.97 in W (105 x 75 mm).
Why this product exists
This breaker provides compact overcurrent protection in applications that need a UL 489 industrial miniature circuit breaker format with DIN rail installation. The C-curve trip profile helps reduce nuisance tripping on circuits with medium inrush current compared with more sensitive trip characteristics.
Compared with similar products
Compared with a B-curve breaker, this C-curve model is typically better suited to loads with moderate inrush. Compared with multi-pole versions, this model protects one ungrounded conductor only. The SP suffix indicates single packaging for this part number.
