2D20UL | Circuit Breaker | 20A | 2-Pole | 277V

The 2D20UL is an industrial circuit breaker engineered for reliability in maintenance, retrofit, and replacement tasks where exact specs matter. With a 20A rating, two poles, and operation at 277V, this model is built to safeguard commercial and light industrial networks that run on higher voltage distribution.

Designed for quick, confident swaps, the 2D20UL uses a two-pole design to interrupt both hot legs, ensuring comprehensive protection for 277V circuits. Its form factor and contact arrangement support straightforward installation in standard panels where the 2-pole, 277V configuration is required.

Key specifications

• Amperage: 20A
• Poles: 2-Pole
• Voltage: 277V

Why this breaker stands out

Unlike generic replacements, the 2D20UL is identified by its precise part number, making compatibility checks simpler and more reliable. This circuit breaker is ideal for maintenance windows, retrofits, and replacements where the exact 2-pole, 277V profile is required, helping you avoid mismatched units that can delay projects.

Use cases and ideal applications

• Commercial lighting and 277V distribution in offices, warehouses, and retail spaces
• Panel retrofits where older breakers no longer meet current safety or code expectations
• Spare parts for service crews to minimize downtime during planned outages
• Replacement for worn or tripped breakers in industrial control circuits operating at 277V

How to verify compatibility

Before ordering, confirm fit and ratings against your panel label. The component’s part number (2D20UL) is the most reliable reference for matching specimens and ensuring you’re selecting the correct unit for your enclosure and wiring configuration.

Installation and safety tips

• Ensure power is fully de-energized and circuits are isolated before replacement.
• Use insulated tools and follow panel manufacturer torque and wiring guidelines.
• Keep a spare 2D20UL on hand for planned maintenance to reduce downtime.

With the 2D20UL, you get a dependable, purpose-built solution for protecting 277V circuits in demanding industrial environments. Uncompromising performance, precise compatibility, and a straightforward replacement path—all in one trusted model.
