Eaton FAZ-K3/1N - 3 A, 480 V, 1-Pole Circuit Breaker | AmpState

Meet the Eaton FAZ-K3/1N — a compact 3 A, 480 V, 1-pole molded case circuit breaker engineered to deliver precise, dependable branch circuit protection in panelboards and load centers. Designed to pair seamlessly with Eaton OEM equipment, it ensures reliable overcurrent and short-circuit protection where space is at a premium.

Why engineers choose the FAZ-K3/1N

• Space-efficient design: A compact molded case form factor makes it ideal for crowded panel spaces, helping you maximize density without compromising protection.
• Thermal-magnetic trip unit: Combines a thermal element for stable overload protection with a magnetic trip for fast, decisive short-circuit clearing—yielding repeatable, predictable performance in everyday operation.
• OEM compatibility: Specifically engineered to drop into matching Eaton load centers and panelboards, reducing installation friction and ensuring consistent trip characteristics.
• Versatile voltage and current rating: 3 A at 480 V enables protection of low-current circuits on higher-voltage systems, making it suitable for residential, commercial, and light industrial applications.
