Eaton FAZ-B25-3N 25 Amp 480 Volt 3-Pole Circuit Breaker

Introducing the Eaton FAZ-B25-3N — a 25A, 480V, 3-pole molded-case circuit breaker designed to deliver dependable branch-circuit protection for panelboards and loadcenters.

Engineered for space efficiency, the compact molded-case design fits neatly into tight panel configurations, freeing room for additional circuits while keeping wiring orderly. Its thermal-magnetic trip unit provides stable, repeatable protection: the thermal element reacts to overloads with precision, while the magnetic element delivers fast, decisive tripping on short circuits — reducing nuisance trips and protecting downstream equipment.

Why this breaker stands out

• Compact, space-saving form factor: Optimizes panel layout in restricted spaces without sacrificing reliability.
• Thermal-magnetic protection: Combines overload protection with fast short-circuit disconnection for robust safety.
• 3-pole, 480V rating: Ideal for 3-phase commercial and light-industrial applications at standard industrial voltages.
• OEM compatibility: Designed to be used with matching Eaton OEM loadcenters and panelboards, ensuring plug‑and‑play replacement and consistent trip characteristics.
• Versatile applications: Suitable for residential, commercial, and light industrial electrical distribution systems requiring reliable 25A protection.

How it works in your system

In a 3-phase 480V setup, the FAZ-B25-3N intercepts and interrupts all three conductors simultaneously on fault conditions. This coordinated response protects wiring, motors, and downstream devices from overcurrent events while maintaining system stability and minimizing downtime.
