Why this 2-pole 277V breaker stands out

Designed for environments where 277V circuits are common—such as lighting controllers, a range of commercial equipment, and certain motor control applications—this breaker provides balanced protection on both hot legs. The 8A rating is well-suited for moderate-load circuits, offering precise current limiting without unnecessary tripping on typical startup surges.

Ideal use cases

• Maintenance: replace aging or failed breakers in 277V panels to restore reliable protection quickly.
• Retrofit: update older installations that require a specific 2-pole, 277V, 8A configuration to meet current safety standards.
• Replacement: when a direct part-number match is needed for seamless compatibility with existing panels and bus arrangements.

Who should consider this breaker

• Facility managers overseeing commercial electrical systems
• Electricians performing panel upgrades, retrofits, or routine maintenance
• Maintenance technicians responsible for ensuring uninterrupted operation of 277V loads

Practical guidance for checkout and installation

To ensure a precise fit, rely on the part number 2D8UL as the primary reference. Before purchasing, verify that your panel’s voltage rating, conductor sizing, and mounting arrangement align with this two-pole, 277V, 8A device. If you’re replacing an existing breaker, compare the current, voltage, pole count, and physical form factor to avoid incompatibilities during installation.
