Circuit Breaker · 5A 2-Pole C Curve DIN Rail UL 489 - Eaton FAZ-C5/2-NA
Eaton FAZ-C5/2-NA is a 5A, 2-pole DIN rail miniature circuit breaker with C-curve tripping for circuits with typical medium inrush loads such as small transformers and pilot devices. Rated for 277/480V AC, with screw terminals and UL 489 / CSA certification for panel and control applications.
What this product is for
This 5A 2-pole miniature circuit breaker is used for branch circuit protection in industrial control panels, machinery, and DIN rail assemblies where overload and short-circuit protection are required.
Use for
Use for 277/480V AC control circuits, small transformers, pilot devices, and other loads where a C-curve breaker is appropriate and medium inrush current is expected. It mounts on standard DIN rail and uses screw terminals for conductor termination.
Avoid for
Avoid using this breaker as a panelboard plug-in breaker or where a different trip curve, pole count, voltage rating, or interrupting rating is required. Confirm equipment approval, conductor sizing, and local code requirements before replacement.
Best for
Best for electricians and panel builders needing a compact UL 489 listed breaker for OEM panels, industrial enclosures, and control systems using two-pole branch protection.
Installed in
Typically installed in industrial control panels, machinery panels, automation cabinets, and DIN rail distribution assemblies. Product size is approximately 1.4 in D x 2.97 in W x 4.13 in H (36 mm D x 75 mm W x 105 mm H).
Why this product exists
This breaker provides compact branch protection where North American approvals, DIN rail mounting, and C-curve tripping are needed. C-curve breakers are commonly used where moderate startup current is expected. Actual suitability depends on the connected load, fault current available, and local electrical code.
Compared with similar products
Compared with lower inrush trip curves, this C-curve model is better suited to loads with typical startup surges. Compared with single-pole models, this 2-pole version disconnects two poles together for matched circuit protection in the same device.
