Circuit Breaker · 3A 1-Pole · C Curve UL 489 Branch Protector · Eaton FAZ-C3/1-N· SP

SKU: EAT-FAZ-C3/1-NA-SP

3A single-pole DIN rail miniature circuit breaker for branch circuit protection with a C-curve trip for typical medium inrush loads such as small transformers and pilot devices. Rated 10 kAIC at 277V AC with screw terminals for control panels and industrial branch wiring.

What this product is for

This Eaton FAZ-C3/1-NA-SP is a 3A, 1-pole UL 489 industrial miniature circuit breaker used for branch circuit protection against overloads and short circuits. It is designed for DIN rail mounting in control panels, OEM equipment, and industrial electrical assemblies.

Use for

Use for 277V AC branch circuits where a 3A breaker is required, especially where medium inrush current is expected. Typical applications include small transformers, pilot devices, control circuits, and panel-mounted branch protection.

Avoid for

Avoid using this breaker where the circuit voltage, available fault current, or application requirements exceed its published ratings. Do not substitute it for a different trip curve, pole count, or interrupting rating without confirming code and equipment requirements.

Best for

Best for electricians, panel builders, and maintenance teams needing a compact DIN rail branch breaker with a C-curve trip characteristic, screw terminals, and UL 489 listing for North American installations.

Installed in

Commonly installed in industrial control panels, machinery panels, OEM assemblies, and commercial electrical enclosures. Approximate body size is 0.7 in D x 2.97 in W x 0.75 in H (18 x 75 x 19 mm), which helps when planning DIN rail space.

Why this product exists

This breaker provides compact branch circuit protection in applications that need a small ampere rating and a C-curve trip profile. Eaton identifies it as suitable where medium levels of inrush current are expected, helping reduce nuisance tripping on startup compared with more sensitive trip characteristics.

Compared with similar products

Compared with supplementary protectors, this NA version is listed as a UL 489 branch protector for North American use. Compared with other trip curves, a C curve is commonly selected for circuits with moderate startup current. Actual suitability depends on the connected load, available fault current, enclosure design, and local electrical code.
