Eaton FAZ-B1.5/2-NA 1.5A 2-Pole 480 V Circuit Breaker Potential Transformer

Introducing the Eaton FAZ-B1.5/2-NA — a purpose-built 2-pole circuit breaker with an integrated potential transformer designed to bring protection and precise monitoring into your electrical distribution. With a 1.5 A current rating and a 480 V operating range, this unit is engineered for reliable performance in demanding industrial and commercial environments.

Key advantages that set this breaker apart

• Integrated potential transformer enables direct, accurate sensing for meters, relays, or protection schemes without the need for additional transformers or wiring drawers. This simplifies panel layout and improves measurement accuracy across the protected circuit.
• Two-pole configuration provides coordinated protection across both conductors, ensuring balanced interruption and safer, more predictable trip behavior in multi-wire circuits.
• Compact, robust design crafted for space-conscious panels while withstanding the rigors of continuous operation in industrial settings.
• Eaton reliability built to align with Eaton protection and control ecosystems, helping you maintain consistency in installation, replacement parts, and long-term serviceability.
• Clear electrical specifications — accepts up to 1.5 A load while rated for 480 V, making it well-suited for distribution, control, and instrumentation applications that require tight current control alongside measurement capabilities.

What problems this model solves

In many panels, protection and monitoring rely on separate devices and complex wiring. The FAZ-B1.5/2-NA consolidates protection with a built-in potential transformer, reducing wiring complexity, saving installation time, and delivering reliable sensing for protective relays and metering equipment. This integration helps prevent measurement error due to mismatched transformers and minimizes potential points of failure in the field.

Who benefits most

• Electrical engineers and panel builders seeking a streamlined solution that pairs circuit protection with accurate sensing for control and instrumentation.
• Maintenance teams looking to simplify spare parts and upgrade paths within an Eaton-compatible ecosystem.
• Facilities managers in industrial and commercial facilities that require dependable protection with integrated measurement capabilities for energy management and uptime.

Ideal use cases

• Instrumentation and control feeders where precise monitoring is essential for safety interlocks and data logging.
• Panelized systems and switchgear assemblies that benefit from reduced component count and simplified wiring.
• Retrofit projects converting standalone protection and metering arrangements into a single, integrated solution.

Practical tips for installation and optimization

To maximize the benefits of the FAZ-B1.5/2-NA, align it with compatible protection relays and metering equipment that can read the integrated transformer output. Verify that your system voltage and current profiles stay within the 480 V and 1.5 A specifications, and plan wiring routes to minimize transit length between the breaker and sensing devices. When replacing an older setup, consider how this integrated solution can reduce enclosure fill and simplify future maintenance tasks.

Why choose this Eaton solution over alternatives

Unlike separate protection devices and transformers, the FAZ-B1.5/2-NA delivers protection and accurate sensing in a single, purpose-built unit. This integration reduces the number of components, simplifies installation, and helps maintain consistent performance across your protection scheme. Its Eaton heritage supports consistent parts availability, streamlined service, and a cohesive approach to system upgrades or expansions.

In summary, the Eaton FAZ-B1.5/2-NA 1.5A 2-Pole 480 V Circuit Breaker Potential Transformer is a targeted, reliable choice for applications that demand precise monitoring alongside robust protection. It’s ideal for panel builders, engineers, and maintenance teams looking to optimize protection schemes without sacrificing measurement accuracy or installation efficiency. Invest in a solution that delivers both safety and insight—right out of the Eaton family.
