Eaton FAZ-K16/1N 16A 480V 1-Pole Circuit Breaker

The Eaton FAZ-K16/1N is a compact, reliable 16A, 480V, 1-pole molded case circuit breaker designed to safeguard electrical circuits in panelboards and loadcenters. Built to deliver dependable branch circuit overcurrent and short-circuit protection, this unit fits where space is at a premium while maintaining strong protection across residential, commercial, and light industrial applications.

Why the Eaton FAZ-K16/1N stands out

• Space-conscious design — a compact molded case meets the demands of modern panels, helping you maximize usable space without compromising protection.
• Thermal-magnetic trip unit — combines a thermal element for overload protection with a magnetic element for fast response to short circuits, delivering stable, repeatable protection performance.
• OEM-ready compatibility — engineered to work with matching Eaton OEM load centers and panelboards, ensuring smooth coordination within your electrical system.
• Versatile across sectors — suitable for residential, commercial, and light industrial circuits that operate in 480V systems, making it a practical choice for diverse panel configurations.
• Specifically rated for 16A at 480V — ideal for protecting branch circuits that require moderate current with high-voltage applications, while helping minimize nuisance trips.

Ideal use cases and scenarios

Use the FAZ-K16/1N to protect individual branch circuits within panelboards and loadcenters that serve commercial spaces, light industrial facilities, or homes with 480V distribution needs. Its single-pole design is well-suited for guarding specific single-phase circuits feeding equipment, receptacle banks, lighting, or control circuits within a 480V system. When space, reliability, and precise protection are priorities, this breaker delivers a clear, consistent performance profile.

Installation, compatibility, and practical tips

• Ensure panel compatibility by using the FAZ-K series with matching OEM load centers and panelboards designed for 480V, 1-pole breakers.
• Verify conductor sizing and torque requirements per manufacturer guidelines to maintain a secure, reliable connection.
• Coordinate protection with upstream devices and the panel’s rating to ensure appropriate short-circuit current interruption levels.
• Install only in installations that comply with applicable electrical codes and local regulations; enlist a qualified electrician for panelwork and commissioning.

Why this matters for safety and reliability

The FAZ-K16/1N’s thermal-magnetic trip mechanism provides a balanced approach to protecting wiring and connected equipment: it reacts to overloads with the thermal element and responds rapidly to short circuits with the magnetic element. That translates to fewer nuisance trips on normal load increase, quicker interruption during faults, and enhanced protection for both people and electrical equipment in a 480V environment.
