## Summary description

The Kanlux KRD10-2/40/30-B is a 2-pole residual current circuit breaker (RCCB) designed for electrical safety. It features a 40A rated current and a 30mA sensitivity threshold. As a Type B device, it provides protection against AC and pulsating DC residual currents, making it suitable for advanced industrial and residential electrical installations requiring high-level fault protection.

## Long description

The Kanlux KRD10-2/40/30-B is a high-performance 2-pole residual current circuit breaker (RCCB) engineered to provide comprehensive electrical safety in modern installations. This device is specifically designed to detect and interrupt electrical circuits when a fault current is present, protecting both users and equipment from potential hazards. By operating with a 40A rated current and a 30mA sensitivity threshold, it ensures reliable performance in diverse electrical environments.
Advantages
The primary advantage of this Type B residual current circuit breaker is its ability to detect not only standard AC residual currents but also pulsating DC components. This makes it a versatile and essential component for systems involving modern power electronics, such as frequency converters, photovoltaic installations, and electric vehicle charging stations. Its robust construction ensures long-term operational stability and high safety standards, meeting the rigorous requirements of contemporary electrical infrastructure.
Suitable for
Photovoltaic (PV) solar power systems
Electric vehicle (EV) charging infrastructure
Frequency converters and variable speed drives
Advanced residential and industrial electrical panels
Equipment with complex power electronics
When it may not be suitable
This device is not intended for use in simple electrical circuits that only require standard Type AC or Type A protection, as it is specifically optimized for complex loads involving DC components. It should not be installed in environments where the electrical load characteristics do not necessitate Type B protection, as this may lead to unnecessary costs and over-specification.
Key specifications
Number of poles: 2
Rated current: 40A
Rated residual operating current: 30mA
Device type: Type B
Application: AC and pulsating DC residual current protection
How to use
The Kanlux KRD10-2/40/30-B must be installed by a qualified electrician in accordance with local electrical regulations and safety standards. It is designed for mounting on a standard DIN rail within a distribution board. 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 and torque settings as specified by the manufacturer. 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 your electrical system requires Type B protection for your specific equipment.
Ensure the 40A rated current matches the requirements of your circuit.
Check the available space in your distribution board for a 2-pole device.
Confirm that the installation environment meets the technical requirements for this RCCB.
Usage recommendations
Regularly test the residual current circuit breaker using the built-in test button at least every six months to ensure the mechanism remains operational and provides continuous protection for your electrical installation.
