Eaton FAZ-C63/3N - 63 A, 480 V, 3-Pole Circuit Breaker | AmpState

The Eaton FAZ-C63/3N is a compact, reliable 63A, 480V, 3-pole molded case circuit breaker designed to guard every essential branch circuit inside panelboards and loadcenters. Built to deliver consistent protection in demanding environments, this unit helps you keep critical systems safe while maximizing space in your electrical enclosure.

• Space-efficient molded-case design: minimizes footprint inside panelboards, freeing up room for additional breakers and easier wiring layouts.
• Thermal-magnetic trip unit: combines precise thermal sensing with immediate magnetic trip if a short circuit occurs, delivering stable, repeatable protection across varying loads and temperatures.
• Three-pole configuration: ideal for balanced protection in 3-phase systems, ensuring coordinated shutdown across all phases in commercial and light industrial applications.
• OEM-ready compatibility: engineered to pair seamlessly with Eaton’s own loadcenters and panelboards for streamlined installation and dependable performance.
• 55–63A class protection at 480V: designed for branch circuit overcurrent and short-circuit protection in environments that demand robust electrical safety at higher voltages.

This breaker is particularly well-suited for electricians and facility managers working on residential, commercial, and light industrial installations where space, reliability, and quick trip response matter. Whether you’re upgrading an aging panel, expanding a 3-phase system, or coordinating protection for critical equipment, the FAZ-C63/3N delivers the dependable performance you expect from Eaton.

Why choose this model: Unlike breakers that rely on a single protection mechanism, the FAZ-C63/3N's thermal-magnetic design provides a balanced response—protecting conductors from overheating while remaining resilient against nuisance trips caused by ambient temperature swings or transient faults. Its 3-pole layout ensures all phases are protected in tandem, reducing the risk of unbalanced faults that can stress equipment.

Practical tips for installation and use:

• Verify your panelboard accepts Eaton FAZ-series molded case breakers to ensure seamless fit and trip coordination.
• Plan wiring in a tidy, labeled manner to maximize the benefits of the compact design and simplify future maintenance.
• Periodically inspect connections for tightness and signs of overheating; the thermal-magnetic trip unit responds to actual current conditions, but secure terminations are still essential for long-term reliability.
• Use this 63A, 480V, 3-pole breaker for branch circuits that require reliable protection against overload and short circuits in three-phase systems.
