Eaton PL6-C25/3 Miniature Circuit Breaker, 3-Pole, C-Curve, 25A, 6kA

The Eaton PL6-C25/3 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical installations. Designed for integration into residential and commercial distribution boards, this device effectively monitors electrical circuits to prevent damage from overloads and short circuits. With its reliable switching mechanism and high-quality construction, it serves as a critical component in maintaining the safety and integrity of AC electrical systems.

Advantages

This circuit breaker offers exceptional reliability and durability, ensuring consistent performance under standard operating conditions. The C-curve tripping characteristic provides a balanced response to current surges, making it suitable for a wide range of applications where moderate inrush currents are expected. Its compact 3-pole design allows for efficient space utilization within electrical panels, while the 6kA breaking capacity ensures that the device can safely interrupt fault currents, thereby protecting downstream equipment and wiring from potential hazards.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Protection of lighting circuits
• General purpose electrical installations
• Small motor control circuits

When it may not be suitable

This circuit breaker is not intended for use in DC electrical systems or high-voltage industrial applications exceeding its rated specifications. It may also be unsuitable for circuits with extremely high inrush currents that require a D-curve characteristic to prevent nuisance tripping.

Key specifications

• Number of poles: 3
• Rated current: 25A
• Tripping characteristic: C-curve
• Breaking capacity: 6kA
• System compatibility: AC electrical systems

How to use

The Eaton PL6-C25/3 is designed for standard DIN-rail mounting within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is snapped onto the rail, and the supply and load conductors are connected to the respective terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 25A rating matches the requirements of your specific circuit load.
• Ensure the 3-pole configuration is appropriate for your three-phase or multi-circuit application.
• Confirm that the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Check the available space in your distribution board for a 3-module wide device.

Usage recommendations

For optimal safety and longevity, regularly inspect the circuit breaker for signs of thermal damage or loose connections. Do not attempt to modify or repair the internal mechanism, as this will void the safety certification and compromise the protection of your electrical system.
