What problems it solves

In three-phase systems, a reliable 3 A protection device at 480 V ensures that wiring and downstream equipment are safeguarded against overcurrent and short circuits. The thermal-magnetic trip curve responds quickly to fault conditions while accommodating normal start-up surges, helping minimize downtime and potential damage to motors, control circuits, and other 3-phase loads.

Practical use cases

Ideal for panelboard upgrades or new installations in small to mid-size commercial spaces, light industrial applications, or residential voltage-mupporting equipment where a compact, three-pole solution is required. Use it where an Eaton-compatible OEM panelboard footprint is desired to maintain a cohesive protective system across the electrical enclosure.

Installation and compatibility guidance

Choose the FAZ-K3/3N when your panel requires a three-pole molded case breaker rated for 480 V and 3 A. To ensure optimal performance, pair it with the corresponding Eaton OEM load center or panelboard. During installation, ensure proper torque on terminals and verify conductor sizing is appropriate for the 480 V system and ambient conditions.

Why choose Eaton FAZ-K3/3N

This breaker combines compact sizing with precise thermal-magnetic protection for reliable circuit safeguarding in demanding electrical environments.
