Eaton FAZ-B7-3 - 7 A, 480 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton FAZ-B7-3—a 7A, 480V, 3-pole molded-case circuit breaker engineered for reliable branch-circuit protection in panelboards and loadcenters. Designed for 3-phase systems, this unit combines compact form with precise protection, making it a practical choice for modern electrical distributions in residential, commercial, and light industrial settings.

What sets the FAZ-B7-3 apart

• Slim molded-case design optimizes panel space and allows denser, neater installations in tight electrical rooms or crowded panels.
• Thermal-magnetic trip unit delivers stable overload protection (thermal) and fast short-circuit response (magnetic), ensuring repeatable protection across varying loads and temperatures.
• OEM panel compatibility calibrated to work with matching Eaton loadcenters and panelboards, helping maintain proper electrical coordination and ease of replacement.
• 3-pole configuration ensures simultaneous disconnection of all three phases, enhancing safety and protecting 3-phase equipment from imbalance or fault propagation.
• Versatile applications suitable for residential, commercial, and light industrial circuits that run at 480V.
