Circuit Breaker · 3A 2-Pole C-Curve DIN Rail Box Terminal Eaton FAZ-C3/2-NA

What this product is for

This 3 A, 2-pole Eaton FAZ series miniature circuit breaker is used to protect branch and control circuits against overloads and short circuits. It is designed for DIN rail mounting in industrial control panels and similar assemblies.

Use for

Use for 277/480 V AC or 230/400 V AC circuits where a 2-pole breaker with a C-curve trip is required. It is commonly selected for circuits with moderate inrush current, including small transformers, pilot devices and control components.

Avoid for

Avoid using this breaker where a different interrupt rating, trip curve, pole configuration or terminal style is required. Do not assume suitability for every branch circuit without confirming panel compatibility, available fault current, conductor size and local code requirements.

Best for

Best for electricians and panel builders needing a compact DIN rail breaker with 3 A protection, 2-pole switching and box-style terminals. The C-curve trip is typically chosen where startup or inrush current is higher than a B-curve device would normally allow.

Installed in

Installed in DIN rail control panels, machinery panels, commercial equipment assemblies and other electrical enclosures using 35 mm DIN rail. Product dimensions are approximately 1.38 in deep x 1.5 in wide (35 mm x 38 mm), with overall height around 2.97 in (75 mm) based on distributor and datasheet listings.

Why this product exists

This breaker provides compact supplementary or miniature circuit protection in applications where panel space is limited and a DIN rail format is preferred. A 2-pole device allows simultaneous protection and switching of two conductors in the same assembly.

Compared with similar products

Compared with higher-amp FAZ breakers, this 3 A model is intended for lighter-load circuits. Compared with B-curve breakers, a C-curve breaker is typically better suited to moderate inrush loads. As a rule of thumb, always verify the breaker curve against the connected load profile and the available fault current before ordering.
