Eaton WMZT1D02 2A 1-Pole 277 V Circuit Breaker

Introducing the Eaton WMZT1D02 2A 1-Pole 277 V Circuit Breaker. This Eaton-manufactured protective device is built for 277-volt branch circuits and provides a precise 2-amp overcurrent protection on a single hot leg. The 1-pole design helps conserve panel space while delivering reliable protection where it matters most.

Key specs

• Current rating: 2 A
• Poles: 1
• Voltage rating: 277 V
• Part number: WMZT1D02

Ideal use cases

277V circuits are common in commercial buildings for lighting, signage, and certain control applications. The WMZT1D02 is well-suited for protecting such dedicated branches—whether you’re powering LED drivers, ballasts, or small control relays—without impacting adjacent circuits.

Why choose this Eaton breaker

Choosing the WMZT1D02 means selecting a component designed to align with Eaton’s protection strategy for 277V systems. Its precise 2A rating ensures sensitive equipment stays safe from overloads, while the single-pole configuration maximizes compatibility in panels that support Eaton’s 1-pole protection devices. Be sure to verify panel compatibility with Eaton’s WM-series style breakers for a seamless installation.

Practical tips

• Use for dedicated 277V lighting or small control circuits where a strict 2A limit is desired.
• Pair with devices that require tight overcurrent protection to minimize nuisance trips.
• Follow local electrical codes and the panel manufacturer’s instructions when installing or replacing this breaker.
