Eaton FAZ-K16/3 - 16 A, 480 V, 3-Pole Circuit Breaker | AmpState

Eaton FAZ-K16/3 is a 16 A, 480 V, 3-pole molded case circuit breaker designed to deliver reliable branch-circuit protection right where you need it—in panelboards and loadcenters. Built for spaces that count, this compact device combines precise protection with practical installation benefits for commercial, residential, and light industrial settings.

Why choose the FAZ-K16/3?

• Compact molded-case design maximizes usable space inside panelboards and loadcenters, making it easier to fit multiple circuits in tighter electrical rooms and smaller enclosures.
• Thermal-magnetic trip unit provides stable, repeatable protection for both overcurrent and short-circuit conditions. The thermal element handles normal load fluctuations smoothly, while the magnetic element delivers fast, decisive tripping when faults occur.
• Three-pole configuration supports three-phase systems, ensuring balanced protection across all phases and simplifying coordination in multi-pole circuits.
• OEM compatibility is designed to align with matching Eaton OEM loadcenters and panelboards, helping you maintain consistent performance and reliable replacement parts across your installation.
• Specifications tailored to demanding environments: 16 A rating, 480 V operation, ideal for distributing power in commercial spaces, light industrial equipment, and residential-scale commercial panels.

What problems does it solve?

• Protects expensive wiring and devices from overcurrent faults, preventing overheated conductors and potential fire hazards.
• Stops fault currents quickly in three-phase circuits, reducing downtime and equipment damage in motor drives, lighting panels, and distribution panels.
• Delivers predictable trip behavior, helping electrical designers and installers achieve safer, more reliable system coordination in mixed-use facilities.

Ideal use scenarios

• New commercial panel installations where space efficiency matters and three-phase protection is required.
• Residential-adjacent commercial setups (small office buildings, retail spaces) needing robust branch protection without bulky breakers.
• Light industrial panels that feed 3-phase equipment, motors, or conveyors where reliable tripping and easy integration with existing Eaton components are priorities.
