3CU15L | Circuit Breaker | 15A | 1-Pole | 240V

The 3CU15L circuit breaker is a purpose-built, industrial-grade protection device designed to safeguard electrical systems with 15A protection on a 1-Pole channel rated for 240V. Built for durability in maintenance, retrofit, and replacement projects, this breaker delivers reliable overcurrent protection when you need it most.

Key specifications

• Amperage: 15A
• Poles: 1-Pole
• Voltage rating: 240V
• Part number: 3CU15L

Why choose the 3CU15L for your project

Unlike generic substitutes, the 3CU15L is a dedicated industrial circuit breaker whose best reference for compatibility is the exact part number. This ensures you’re matching the intended fit, electrical ratings, and mounting style for your panel or enclosure. When timing and reliability matter, using the correct 3CU series device helps minimize downtime and unwanted tripping in critical applications.

Compatibility and fit guidance

• Use the part number 3CU15L as the primary reference to confirm compatibility with your panel, enclosure, or protection scheme.
• Before ordering, verify that your application requires single-pole, 240V protection at 15 amps.
• Best results come from matching the exact specifications rather than substituting different amperage, pole count, or voltage ratings.

Ideal use cases

• Maintenance and retrofit projects where an exact replacement is needed to restore original protection levels.
• Replacement of aging or failing breakers in industrial panels that require 240V, 15A single-pole protection.
• New installation scenarios modeled after existing 3CU15L specifications to maintain consistency across circuits.

Practical installation and care tips

• Always confirm fit and ratings before ordering to avoid compatibility issues in the field.
• Shut off power and follow standard electrical safety practices when installing or replacing a breaker.
• Handle with care to prevent mechanical damage to the mounting lugs and terminals; ensure secure seating in the panel bus if applicable.
• Keep a record of the part number (3CU15L) for future maintenance cycles and panel documentation.

For reliable, component-level protection in industrial electrical systems, the 3CU15L 15A 1-Pole 240V circuit breaker stands out as a precise, specification-driven choice—especially when your goal is a precise match to existing equipment and long-term performance.
