Eaton FAZ-C5/3 5A 3-Pole 480 V Circuit Breaker Potential Transformer

Meet the Eaton FAZ-C5/3 — a purpose-built, 3-pole circuit breaker with an integrated potential transformer for demanding 480 V three-phase systems. Designed for reliability in industrial environments, this model delivers precise protection and streamlined measurement in a single, compact unit.

• Part Number: FAZ-C5/3
• Current Rating: 5 A
• Poles: 3
• Voltage Rating: 480 V

What sets the FAZ-C5/3 apart is the combination of protection and measurement capabilities in one device. The built-in potential transformer supports accurate monitoring and relay-friendly signaling, making it an efficient choice for panels that require reliable fault interruption alongside real-time load data. In practice, this means fewer separate components to install, connect, and maintain, helping to shorten commissioning times and reduce wiring complexity.

Ideal use scenarios include:

• Three-phase motor protection in 480 V industrial drives and equipment
• Power distribution panels within manufacturing settings requiring integrated measurement
• OEM panel assemblies where space, wiring efficiency, and reliability are critical
• Industrial process control environments that benefit from direct metering and protection signals

Key benefits you’ll notice in daily operation:

• Integrated protection and measurement reduce the need for additional CTs and metering hardware
• Three-pole design ensures synchronized protection across all phases, improving fault handling and system stability
• Solid Eaton engineering and proven performance under industrial loads
• Simple, scalable solution for mid-size to large electrical distribution schemes

Practical tips for integration and use:

• Verify system voltage and phase configuration aligns with the 480 V, 3-phase specification
• Plan for accessible wiring routes to accommodate the integrated transformer connections
• Coordinate with your protection and metering relays to leverage the transformer outputs for accurate monitoring
• Install by qualified personnel following applicable electrical codes and safety practices

Whether you’re refurbishing a panel, designing a new distribution block for an automation line, or upgrading a facility’s protection and metering capabilities, the Eaton FAZ-C5/3 delivers a focused, reliable solution. Its compact combination of a 5 A current path, 3-pole 480 V rating, and built-in potential transformer addresses both safety and visibility — so you can protect equipment, monitor performance, and keep operations running smoothly.
