Eaton FAZ-K50/1N - 50 A, 480 V, 1-Pole Circuit Breaker | AmpState

Eaton FAZ-K50/1N is a 50-amp, 480-volt, 1-pole molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection inside panelboards and loadcenters. Built to fit seamlessly with Eaton’s OEM load centers, this unit combines compact form with robust protection for demanding electrical environments.

Why this breaker stands out

• Space-efficient design: The compact molded case format helps maximize panel space, making it easier to configure and expand residential, commercial, or light industrial electrical layouts without sacrificing protection.
• Thermal-magnetic trip unit: Provides stable, repeatable protection by combining thermal overload sensing with magnetic short-circuit protection. This means fewer nuisance trips during normal load fluctuations and fast response to short circuits when they occur.
• OEM-compatible performance: Specifically engineered to couple with matching Eaton OEM load centers and panelboards, ensuring reliable fit, consistent trip characteristics, and straightforward replacement.
• Versatile voltage rating: Rated for 480V systems, making it suitable for a range of commercial and light industrial applications that operate at higher line voltages.

What it protects and how it’s used

This 1-pole circuit breaker serves as the critical guard against branch-circuit overcurrent and short-circuit events. In practical terms, it sits in a panelboard or loadcenter to safeguard individual circuits—such as lighting, receptacle runs, or control circuits—by interrupting current flow when a fault or overload is detected. Its 50A rating is ideal for mid-range branch circuits in commercial spaces or residential setups with higher load demands.

Ideal applications

• Residential panels with higher-demand circuits requiring reliable protection at 480V-capable systems
• Commercial electrical rooms and small office fit-outs where space is at a premium
• Light industrial panelboards that need dependable, fast-tripping protection for single-phase circuits

Practical guidance for installation and maintenance

Choose the FAZ-K50/1N when you’re configuring or upgrading panelboards that require a compact, reliable single-pole breaker with 480V capability. For best results, pair it with the corresponding Eaton load centers designed to accept this exact model to ensure consistent electrical performance and straightforward replacement. Regular inspection of connections and mounting integrity will help maintain the stability of protection and minimize nuisance trips.

Why choose Eaton over generic solutions

Unlike generic breakers, the FAZ-K50/1N is engineered to harmonize with Eaton’s panel infrastructure, delivering predictable trip behavior and a streamlined form factor that preserves valuable panel space. The combination of a molded case enclosure and a thermal-magnetic trip mechanism translates to reliable protection in everyday service and through the aging cycles of commercial systems, reducing downtime and maintenance complexity.
