1CU15R | Circuit Breaker | 15A | 1-Pole | 277V

Meet the 1CU15R Circuit Breaker — a purpose-built industrial safety device designed for 277V single-pole circuits. With a precise 15A rating, this breaker is tailored for maintenance, retrofit, and replacement projects where exact specifications matter and downtime is costly.

Why choose the 1CU15R?

• Single-pole, 15A protection designed for 277V electrical systems, ideal for controlling a single leg of the distribution circuit.
• Rugged construction engineered for reliable operation in commercial and light industrial environments.
• Fast, predictable fault interruption helps minimize downtime and protects connected equipment in critical loads.
• Dedicated part number reference (1CU15R) provides a precise compatibility signal during sourcing and replacements.
• Direct replacement path for panels and enclosures that require a 1-Pole 277V breaker with a 15A rating.

Key specifications

• Amperage: 15A
• Poles: 1-Pole
• Voltage: 277V

Important compatibility note: Confirm fit and ratings before ordering. The part number 1CU15R is the best reference for compatibility with your panel or equipment. If your system requires a 1-Pole 277V breaker rated at 15A, this unit is designed to meet that specification.

Ideal use cases

• Maintenance: swap-in replacements during routine service to minimize equipment downtime.
• Retrofit: update aging panels to current 277V single-pole protection without changing circuitry.
• Replacement: straightforward substitute for failed breakers in 277V circuits serving lighting, motors, or other single-leg loads.

Practical considerations

Install only in panels that accommodate 1-Pole 277V breakers and follow all applicable electrical codes. For best results, verify the exact part reference (1CU15R) against your panel’s documentation before purchase.
