Eaton PFL6-20/1N/B/03 Residual Current Circuit Breaker with Overcurrent Protection 1P+N 20A 300mA Type AC

The Eaton PFL6-20/1N/B/03 is a high-quality residual current circuit breaker with overcurrent protection, commonly known as an RCBO. This device is engineered for 1P+N electrical systems, combining the functions of a miniature circuit breaker and a residual current device into a single, compact unit. It is designed to monitor electrical circuits for faults, providing comprehensive protection against overloads, short circuits, and dangerous residual currents, thereby enhancing the safety of electrical installations in both residential and commercial environments.

Advantages

The primary benefit of this Eaton RCBO is its space-saving design, which integrates two critical safety functions into one module, simplifying installation and reducing the space required in distribution boards. It offers reliable performance in detecting AC residual currents, ensuring that the power supply is disconnected promptly in the event of a fault. The robust construction ensures long-term operational stability, while the clear status indicators allow for easy monitoring of the circuit condition, contributing to a safer and more efficient electrical infrastructure.

Suitable for

• Residential electrical distribution boards
• Commercial office power circuits
• Protection of lighting and socket circuits
• General electrical installations requiring combined overload and leakage protection

When it may not be suitable

This device is specifically designed for Type AC residual current detection and may not be suitable for circuits where DC components are present, such as those connected to certain types of modern electronic equipment or variable frequency drives. It is also not intended for use in high-current industrial applications exceeding its 20A rating.

Key specifications

• Rated current: 20A
• Residual current sensitivity: 300mA
• Configuration: 1P+N
• Type: AC
• Function: Combined RCBO

How to use

The installation of this RCBO should be performed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting onto a standard DIN rail within a distribution enclosure. Ensure that the supply cables are correctly connected to the input terminals and that the load is connected to the output terminals, observing the correct polarity for the 1P+N configuration. Once installed, the device can be manually switched on or off using the front lever, and the test button should be used periodically to verify the functionality of the residual current mechanism.

What to consider before purchase

• Verify that the 20A rated current matches the requirements of your circuit load.
• Ensure the 300mA sensitivity is appropriate for the intended application, as this level is typically used for fire protection rather than direct contact protection.
• Confirm that the electrical system is compatible with Type AC residual current devices.

Usage recommendations: It is recommended to perform a functional test using the integrated test button at least every six months to ensure the device remains in optimal working condition.
