Eaton FAZ-B50-1N 50 Amp 480 Volt 1-Pole Circuit Breaker

The Eaton FAZ-B50-1N is a 50A, 480V, 1-pole molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection for panelboards and load centers. Its compact size and precise trip performance make it an ideal choice for industrial and commercial electrical layouts where space and reliability matter.

• Compact molded case design maximizes panel space, allowing cleaner installations and easier expansion in crowded electrical rooms.
• Thermal-magnetic trip unit provides stable overload protection with a predictable thermal response and rapid magnetic trip for short circuits, reducing nuisance trips while safeguarding connected equipment.
• OEM panel compatibility is built in—designed to align with matching load centers and panelboards, simplifying replacements and upgrades without compromising fit or performance.
• Versatile across applications suitable for residential, commercial, and light industrial environments that require 50A protection at 480V.
• 1-pole configuration supports single-phase circuits common in 480V distribution schemes, delivering straightforward protection for individual feeders and control circuits.

Why this matters in real-world setups: protecting a panelboard or load center from overcurrent and short circuits is essential to prevent equipment damage and unplanned downtime. The FAZ-B50-1N’s thermal-magnetic design offers repeatable protection across varying loads—thermal protection handles gradual overloads, while magnetic action responds quickly to faults. This combination helps maintain safe, stable operation for your critical electrical infrastructure.

Practical use cases include feeding 480V single-phase loads in industrial control panels, commercial equipment mains, lighting feeders, and other branch circuits within panelboards that require reliable, code-aligned protection. Its form factor and trip characteristics are well-suited for retrofit projects where OEM compatibility and precise protection behavior are important.
