Eaton FAZ-K3/2 - 3 A, 480 V, 2-Pole Circuit Breaker | AmpState

The Eaton FAZ-K3/2 is a 3A, 480V, 2-pole molded case circuit breaker designed to deliver reliable branch circuit protection for panelboards and loadcenters. Its compact, molded-case construction makes it an ideal fit where space is at a premium, helping you maximize panel capacity without sacrificing safety or performance.

Why this breaker stands out

• Space-efficient design—the compact molded-case form frees up valuable panel space, supporting denser, cleaner installations in both new builds and upgrades.
• Thermal-magnetic trip unit—provides stable, repeatable protection by responding to both overload conditions (thermal) and short circuits (magnetic), ensuring dependable performance across varying loads and temperatures.
• OEM compatibility—specifically engineered to integrate with matching Eaton OEM load centers and panelboards, reducing replacement headaches and maintaining system integrity.
• Versatile applicability—suitable for residential, commercial, and light industrial applications where precise branch circuit protection at 480V is required.

Ideal use scenarios

In commercial spaces with dense panel configurations, the FAZ-K3/2 helps you protect lighting and small equipment circuits without expanding the panel. It’s well-suited for light industrial environments where 480V distribution is common and space-efficient protection is a priority. For retrofit projects, its compatibility with Eaton load centers ensures a smooth, reliable upgrade path that preserves system coordination and protection levels.

How it protects and why it matters

The combination of thermal and magnetic tripping means the FAZ-K3/2 responds quickly to short circuits while minimizing nuisance trips during temporary inrush events. This results in fewer interruptions for everyday loads and greater confidence in your electrical protection strategy. By using a breaker with a dedicated 3A rating, you’re safeguarding sensitive control circuits and smaller branch circuits without over-protecting, which can lead to unnecessary downtime.

Practical guidance for installation and compatibility

• Verify that your panelboard or loadcenter is compatible with Eaton FAZ-K3/2 to ensure proper fit and coordination with existing devices.
• Use as a dedicated 2-pole protection device for circuits that require 480V operation, keeping clear labeling and wiring practices for safety and maintenance clarity.
• Plan for future expansion by pairing with compatible OEM components to maintain a cohesive protection scheme across the distribution system.
• Consult a qualified electrician for installation in accordance with local electrical codes and standards.

Engineered for performance, precision, and compatibility, the Eaton FAZ-K3/2 3A 480V 2-Pole Circuit Breaker is a thoughtful choice for reliable branch circuit protection in panels where space, timing, and coordination matter most.
