Eaton WMZT2D16 16A 2-Pole 277 V Circuit Breaker Potential Transformer

The Eaton WMZT2D16 16A 2-Pole 277 V Circuit Breaker Potential Transformer is a purpose-built protection device designed for commercial and industrial electrical systems operating at 277 volts. With a 16 ampere current rating and two poles, it protects both hot lines simultaneously, delivering quick, coordinated shutdown to minimize damage and reduce arc risk in fault conditions. This part number WMZT2D16 is a trusted choice for reliable circuit protection in Eaton-based ecosystems.

Key specifications

• Part Number: WMZT2D16
• Current rating: 16 A
• Poles: 2
• Voltage rating: 277 V
• Type: Circuit Breaker Potential Transformer

Why this two-pole design matters

Two-pole protection ensures both conductors in a 277 V circuit are interrupted together. This coordinated disconnection improves safety for installers and occupants, helps prevent neutral or ground faults from persisting, and works seamlessly with Eaton panelboards and distribution equipment that rely on consistent, coordinated breaker behavior.

Ideal use cases

• 277 V lighting and power distribution circuits in commercial facilities, retail spaces, and office buildings
• HVAC control circuits and other 277 V applications where reliable protection on both legs is essential
• Systems within Eaton-based electrical infrastructures that require a compact, two-pole protective device

What sets it apart

Unlike single-pole breakers, the WMZT2D16 delivers synchronized interruption on both lines, enhancing safety and trip reliability in 277 V environments. Its design is tailored to integrate with Eaton equipment, ensuring compatibility and consistent performance across your protection scheme.

Practical installation insights

• Install in compatible Eaton panels or enclosures designed for 2-pole, 277 V protection
• Verify circuit amperage aligns with the 16 A rating to avoid nuisance trips on normal operation
• Plan for straightforward maintenance and predictable fault isolation within your electrical distribution system

What you can expect in operation

Users gain calm confidence from reliable overcurrent protection that responds quickly to faults, helping preserve connected equipment and maintain safer, more stable electrical environments. The WMZT2D16 is a straightforward, durable solution for applications requiring robust 2-pole, 277 V circuit protection.
