3CU10L | Circuit Breaker | 10A | 3-Pole | 480V

The 3CU10L industrial circuit breaker is designed to deliver dependable overcurrent protection for 3-phase 480V systems. With a precise 10A rating and three poles, it’s a purpose-built solution for maintenance, retrofit, and replacement tasks where exact specifications matter. When your panel or distribution network requires a like-for-like part, 3CU10L ensures seamless compatibility and consistent performance under demanding conditions.

Key to its value is the ability to protect critical three-phase feeders and equipment without compromising on safety or reliability. The 3CU10L is positioned for environments where downtime is costly and uptime is essential, helping to prevent damage from overcurrent events while keeping service interruptions to a minimum.

Key Specifications

• Amperage: 10A
• Poles: 3-Pole
• Voltage: 480V

Important compatibility note: Confirm fit and ratings before ordering. The part number 3CU10L is the best reference for ensuring a correct match with your existing panel or equipment.

Ideal use cases

• Maintenance projects where a precise 3-pole, 480V, 10A breaker is required to restore protection quickly.
• Retrofit or upgrade scenarios that demand a like-for-like replacement to maintain existing electrical architecture.
• Replacement of failing breakers in industrial panels, switchboards, or distribution gear that operate at 480V three-phase systems.

Why choose this 3CU10L in place of other options? Its exact specifications reduce installation guesswork and downtime, ensuring you restore protected circuits to their original design intent. By aligning the exact amperage, pole configuration, and voltage, you minimize the risk of compatibility gaps and preserve the protection scheme your equipment relies on.

Practical considerations for successful deployment include verifying that the panel’s rating, trip characteristics, and mounting footprint align with the 3CU10L. When in doubt, reference the part number first to confirm compatibility and maintain consistent protective performance across your three-phase network.
