Eaton FAZ-D40/1N - 40 A, 480 V, 1-Pole Circuit Breaker | AmpState

Engineered for dependable protection in 480-volt panel environments, the Eaton FAZ-D40/1N is a 40A, 1-pole molded case circuit breaker designed to guard branch circuits from overcurrent and short circuits with precision and efficiency. Its compact form helps maximize panel space while delivering consistent protection where it matters most.

What sets the FAZ-D40/1N apart is its thermal-magnetic trip unit, which provides stable, repeatable protection across varying load conditions. The thermal element handles normal overloads gracefully, while the magnetic element delivers an instantaneous response to short circuits, reducing potential damage to equipment and wiring. This combination delivers predictable trip behavior that you can trust in critical commercial and light industrial environments.

Key benefits

• Space-efficient design: A compact molded case footprint that fits neatly inside panelboards and load centers, helping you maximize usable panel capacity.
• Reliable protection: Non-adjustable thermal-magnetic trip ensures consistent response to overloads and short circuits, lowering the risk of nuisance tripping.
• OEM-grade compatibility: Designed to be used with matching Eaton OEM load centers and panelboards for seamless integration and dependable performance.
• Versatile applications: Suitable for residential, commercial, and light industrial installations where 480V distribution is standard.
