Eaton FAZ-K1/1N - 1 A, 480 V, 1-Pole Circuit Breaker | AmpState

Meet the Eaton FAZ-K1/1N — a purpose-built, 1-pole molded case circuit breaker designed to deliver dependable branch-circuit protection inside panelboards and loadcenters. With a compact footprint and a precise thermal-magnetic trip unit, this breaker provides stable and repeatable protection for 1-amp circuits in 480-volt systems.

Why this breaker stands out

• Space-efficient design: The compact molded-case form minimizes panel intrusion, helping you fit more circuits without expanding the enclosure.
• Thermal-magnetic protection you can trust: Combines overload and short-circuit protection in one unit for predictable trips and safer system operation.
• 1A at 480V, 1-pole: Precisely suited for low-current control or signaling circuits within commercial or light industrial distribution setups.
• OEM-friendly compatibility: Specifically designed to pair with matching Eaton OEM loadcenters and panelboards for guaranteed fit and coordinated performance.
• Versatile application: Ideal for commercial and light industrial panels where compact, reliable 480V single-pole protection is required.

Installation and real-world use

This breaker shines in panelboards and loadcenters that require compact space utilization without sacrificing protection quality. Use it in commercial or light industrial environments where 480V single-pole distribution is standard, and you need reliable protection for low-current circuits. Because it’s designed to be used with matching Eaton OEM panel components, you’ll achieve proper coordination, consistent trip characteristics, and straightforward replacement when maintenance is needed.

Use-case scenarios

• Protecting a small 480V control circuit feeding industrial equipment or HVAC systems in a commercial facility.
• Replacing a failed 1A 480V breaker in an Eaton panelboard to restore a critical control or signaling circuit without overhauling the panel.
• Installing in new construction where space-efficient, reliable 1-pole protection is required for dedicated 480V distribution branches.

Tips for best results

• Confirm panel compatibility by using the FAZ-K1/1N with Eaton loadcenters or panelboards specified by the OEM to ensure proper fit and coordinated trip performance.
• Verify the panel’s interrupting rating and ensure your 480V single-pole circuit aligns with safe operating limits.
• Regularly inspect for signs of wear or nuisance tripping; if trips occur at low load, reevaluate connected equipment or circuit protection sizing.
