Eaton WMZT3D25T 25A 3-Pole 277 V Circuit Breaker

The Eaton WMZT3D25T is a purpose-built 25-amp, 3-pole circuit breaker designed specifically for 277V AC applications. With three poles working in concert, this breaker provides reliable protection across all phases of a 3‑phase distribution system, making it a dependable choice for commercial environments that rely on 277V circuits.

Key specifications

• Current rating: 25 A
• Poles: 3
• Voltage rating: 277 V
• Part number: WMZT3D25T

Why this 3-pole design matters

In 277V three-phase layouts, balanced protection across all lines reduces the risk of partial faults damaging equipment. The WMZT3D25T’s triple-pole configuration ensures simultaneous disconnection on all phases, helping to safeguard wiring, motors, and lighting circuits from overloads and fault currents.

Ideal use cases

• 277V three-phase lighting and small motor circuits in commercial buildings, offices, retail spaces, and institutions
• Panel protection for 3‑phase distribution networks where consistent phase protection is essential
• Replacement or retrofit projects requiring an Eaton-branded, compatible 25A 3-pole breaker

What makes it a smart choice

Choosing the WMZT3D25T means aligning with Eaton’s engineering for compatible panel integration and predictable performance. The 25A rating is well-suited for protecting mid-sized loads typical in commercial settings, while the 3-pole architecture provides balanced protection across all conductors, helping to extend the life of connected equipment and maintain system safety.
