Eaton PL6-B4/1N Miniature Circuit Breaker, 1P+N, 4A, 6kA, B-Curve

The Eaton PL6-B4/1N is a professional-grade miniature circuit breaker engineered to provide dependable protection for electrical circuits in both residential and commercial environments. This device features a 1P+N configuration, allowing for the simultaneous disconnection of both the phase and neutral conductors, which enhances safety during maintenance and fault conditions. With a rated current of 4A and a robust 6kA breaking capacity, it is designed to handle standard electrical loads while effectively mitigating the risks associated with overloads and short circuits.

Advantages

This circuit breaker stands out due to its high manufacturing standards and reliable performance under varying electrical conditions. The B-type tripping characteristic ensures that the device reacts appropriately to minor surges, making it ideal for circuits with low inrush currents. Its compact design allows for efficient space utilization within distribution boards, while the clear status indication and durable construction ensure long-term operational stability and ease of integration into existing electrical systems.

Suitable for

• Residential lighting circuits
• Small household appliance power lines
• Control circuits in commercial buildings
• Protection of sensitive electronic equipment with low starting currents

This circuit breaker may not be suitable for applications involving high-power inductive loads, such as large motors or heavy-duty compressors, which typically require a C or D tripping curve to prevent nuisance tripping during startup. It is also not intended for use in circuits exceeding its 4A rated current capacity.

Key specifications

• Rated current: 4A
• Number of poles: 1P+N
• 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 snapped onto a standard DIN rail within an enclosure. Ensure that all wire connections are tightened to the manufacturer's specified torque to prevent overheating and ensure a secure electrical contact. Once installed, the toggle switch can be used to manually disconnect or reconnect the circuit as needed.

What to consider before purchase

• Verify that the 4A rating matches the load requirements of your specific circuit
• Ensure the B-curve characteristic is appropriate for your connected devices
• Check available space in your distribution board for a 1P+N module
• Confirm compatibility with existing DIN rail mounting systems

For optimal safety and performance, regularly inspect the circuit breaker for signs of physical damage or discoloration and test the functionality of the switching mechanism periodically. Ensure that the total load on the circuit does not exceed the rated current to avoid unnecessary tripping.
