• Pole configuration: 1-Pole
• Voltage rating: 120 V
• Part number: BRN115A1CS
• Brand: Eaton

Why this matters

Designed for single-hot-leg protection in standard 120V panels, this 115A breaker provides targeted safeguard for high-load branches. Its 1-pole configuration keeps wiring simple and protects the circuit it serves without impacting neighboring circuits, making it a reliable choice for residential or light commercial installations where a dedicated high-load 120V circuit needs robust interruption capability.

Ideal use cases

Replace a worn or blown breaker on a 120V panel that requires a BRN115A1CS-style unit. It’s suited for single-circuit protection in environments where heavy loads are present on one leg of a 120V system, helping prevent overheating and electrical damage while maintaining overall panel reliability.

How it compares to alternatives

This unit focuses on 120V, single-pole protection with a relatively high 115A rating, making it the right fit for specific high-load branch circuits. It is not intended for 240V or multi-wire configurations, which demand different breaker types or arrangements.

Practical installation tips

• Verify panel compatibility and ensure the circuit requires 115A protection before replacement.
• Power off the main breaker and follow proper safety procedures during installation.
• Keep the exact part number BRN115A1CS on hand for future replacements or service needs.
