Eaton PL6-B25/3 Miniature Circuit Breaker 3P 25A 6kA B-Curve

The Eaton PL6-B25/3 is a high-quality 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in both residential and commercial environments. With a rated current of 25A and a robust 6kA breaking capacity, this device is designed to detect and interrupt electrical faults such as overloads and short circuits, thereby safeguarding your wiring and connected equipment from potential damage.

Advantages

This circuit breaker offers exceptional reliability and safety for modern electrical distribution systems. Its B-type tripping characteristic makes it particularly effective for applications where low-level short-circuit protection is required, such as lighting and heating circuits. The compact 3-pole design allows for efficient space utilization in distribution boards, while the durable construction ensures long-term operational stability and consistent performance under standard electrical loads.

Suitable for

• Residential electrical distribution boards
• Commercial lighting and heating circuits
• Protection of general-purpose electrical installations
• Systems requiring 3-phase power distribution

This device may not be suitable for industrial applications involving high-inrush current equipment, such as large motors or transformers, where a C or D-curve breaker would be more appropriate to prevent nuisance tripping. It is also not intended for use in DC circuits unless specifically rated for such applications.

Key specifications

• Number of poles: 3
• Rated current: 25A
• Breaking capacity: 6kA
• Tripping characteristic: B-curve
• Mounting type: DIN rail

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed to be mounted onto a standard DIN rail within a distribution enclosure. Ensure that the supply voltage and load requirements are compatible with the breaker specifications before installation. Once mounted, connect the incoming and outgoing conductors to the appropriate terminals, ensuring all connections are tightened to the manufacturer's specified torque.

What to consider before purchase

• Verify that the 25A rating matches your circuit load requirements
• Ensure the 3-pole configuration is compatible with your electrical system
• Check that the B-curve characteristic is suitable for your specific load type
• Confirm available space in your distribution board for a 3-module wide device

For optimal safety and longevity, regularly inspect the circuit breaker for signs of physical damage or discoloration and ensure that all terminal connections remain secure over time.
