Eaton PFL6-20/1N/C/03 Residual Current Circuit Breaker with Overcurrent Protection, 1P+N, 20A, 0.3A, Type AC

The Eaton PFL6-20/1N/C/03 is a high-quality residual current circuit breaker with overcurrent protection, commonly known as an RCBO. This device is engineered to provide comprehensive protection for 1P+N electrical circuits by combining the functions of a miniature circuit breaker and a residual current device in a single compact unit. It is designed to detect and interrupt both overcurrent conditions, such as short circuits and overloads, and earth leakage currents, thereby safeguarding both the electrical installation and the users from potential hazards.

Advantages

The primary advantage of this Eaton RCBO is its space-saving design, which integrates two critical safety functions into one module, simplifying installation in distribution boards. It offers reliable performance in residential and commercial environments, ensuring that electrical faults are addressed promptly. The device is built to high manufacturing standards, providing consistent sensitivity and durability, which contributes to the long-term safety and stability of the electrical system.

Suitable for

• Residential electrical distribution boards
• Commercial building power circuits
• Protection of final circuits against overloads and short circuits
• Prevention of electric shock caused by earth leakage currents

When it may not be suitable

This device is designed for AC type leakage current detection and may not be suitable for circuits containing electronic equipment that produces DC components or high-frequency leakage currents, where type A or B devices might be required. It is also not intended for use in industrial environments with specific high-power requirements that exceed its 20A rating.

Key specifications

• Rated current: 20A
• Residual current sensitivity: 0.3A
• Number of poles: 1P+N
• Type: AC
• Tripping characteristic: C

How to use

The device should be installed by a qualified electrician in accordance with local electrical regulations. It is mounted onto a standard DIN rail within a distribution enclosure. Ensure that the supply cables are correctly connected to the input terminals and the load cables to the output terminals, observing the polarity markings for the phase and neutral conductors. Once installed, the device can be manually switched on or off using the toggle lever, and the integrated test button should be used periodically to verify the functionality of the residual current protection mechanism.

What to consider before purchase

• Verify that the 20A rated current matches the requirements of your circuit.
• Ensure the 0.3A sensitivity is appropriate for the intended application, as this is typically used for fire protection rather than direct contact protection.
• Check that the installation space is compatible with the 1P+N modular dimensions.
• Confirm that the AC type is sufficient for the connected loads.

Usage recommendations: It is recommended to perform a functional test using the integrated test button at least every six months to ensure the residual current mechanism remains operational. Always ensure the device is kept free from dust and moisture within the distribution board.
