Eaton FAZ-D16/2 16A 2-Pole 277 V Circuit Breaker Potential Transformer

Discover the Eaton FAZ-D16/2, a purpose-built circuit breaker engineered for reliable protection in 277 V commercial electrical systems. With a 16 A current rating and a 2-pole design, this unit protects both hot conductors in each circuit, delivering decisive overcurrent protection while preventing nuisance trips on multi-feed loads.

The FAZ-D16/2 is specifically configured for 277 V applications, making it an ideal choice for office buildings, retail spaces, and other commercial environments where lighting and electrical distribution run at higher line voltages. By choosing a two-pole configuration, you ensure simultaneous isolation of both poles, which enhances fault clearance and improves overall panel safety and reliability.

Key capabilities at a glance:

• Part Number: FAZ-D16/2
• Current rating: 16 A
• Poles: 2
• Voltage rating: 277 V
• Special feature: Designed for integration with metering setups using a potential transformer—enabling safe, accurate monitoring of load and voltage in monitored installations

Why this breaker stands out

What sets the FAZ-D16/2 apart is its combination of precise protection and field-ready versatility. In environments where 277 V distribution is standard, this breaker delivers dependable interruption during overloads or short-circuit conditions, helping minimize equipment damage and downtime. The 2-pole construction is particularly valuable in protecting multi-wire branch circuits and ensuring that both phases are de-energized together for safer maintenance and service continuity.

Ideal use cases

• 277 V branch circuits powering commercial lighting, HVAC controls, or distributed power in offices and retail spaces
• Multi-wire circuits where simultaneous de-energization of two hot legs is required for safety
• Metering-forward installations where a potential transformer provides scaled signals for energy monitoring and performance analysis

Practical installation tips

For optimal performance, pair the FAZ-D16/2 with compatible Eaton panels and enclosures designed for 277 V service. Verify the line and load connections match the device labeling, and ensure secure torque on terminals to maintain a solid connection under load. If your setup includes monitoring or metering equipment, plan the wiring to accommodate the potential transformer interface without compromising clearance or accessibility for future servicing.

Whether you’re upgrading an aging panel, wiring a new commercial space, or configuring a metering-ready distribution, the Eaton FAZ-D16/2 16A 2-Pole 277 V Circuit Breaker is built to deliver dependable protection with practical versatility. It’s the right choice when you need clear, reliable overcurrent protection for high-voltage commercial applications, backed by Eaton’s engineering and field-proven performance.
