## Long description

The Legrand DX3 RCBO 2P 20A B-Curve 30mA Type A is a professional-grade electrical protection device that combines the functions of a miniature circuit breaker and a residual current device in a single unit. Designed for safety and reliability, this component is engineered to safeguard electrical circuits against overloads, short circuits, and dangerous leakage currents. It is an essential element for modern electrical distribution boards, providing comprehensive protection for both residential and commercial installations.
Advantages
This device offers a compact solution by integrating two protective functions into one housing, which saves valuable space in electrical distribution panels. The Type A sensitivity ensures reliable detection of both alternating and pulsating direct residual currents, providing a higher level of safety compared to standard AC types. The B-curve tripping characteristic is specifically optimized for circuits with low inrush currents, making it ideal for general lighting and socket outlets. Its robust construction and high-quality materials ensure long-term durability and consistent performance under various operating conditions.
Suitable for
Residential electrical distribution boards
Commercial office lighting circuits
General-purpose socket outlet protection
Protection of sensitive electronic equipment
Renovation of existing electrical installations
When it may not be suitable
This device is not intended for use in circuits with high inrush currents, such as those powering large motors or industrial machinery, where a C or D curve breaker would be more appropriate. It is also not suitable for DC-only electrical systems or environments requiring specific industrial-grade protection beyond standard residential and commercial requirements.
Key specifications
Rated current: 20A
Number of poles: 2P
Tripping characteristic: B-curve
Residual current sensitivity: 30mA
Type: A
How to use
The Legrand DX3 RCBO should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for DIN rail mounting within a distribution board. Ensure that the supply cables are correctly connected to the input terminals and that the load circuit is connected to the output terminals. After installation, the device should be tested using the integrated test button to verify its mechanical and electrical functionality.
What to consider before purchase
Verify that the 20A rating matches the requirements of your circuit wiring
Ensure the B-curve characteristic is suitable for your specific load type
Check the available space in your distribution board
Confirm that Type A protection meets the safety standards required for your equipment
Usage recommendations
Regularly test the device using the test button at least every six months to ensure the residual current mechanism remains operational. If the device trips frequently, inspect the circuit for insulation faults or overload conditions before resetting.
