## Summary description

The ABB DS301CA-B16 is a high-quality miniature circuit breaker designed for electrical protection. It features a 16A rated current, 1P+N configuration, and 30mA sensitivity, making it ideal for residential and commercial safety applications. Operating at 230V and 50-60Hz, this device provides reliable protection against overcurrent and residual current faults. It is built to IP20/IP40 standards for safe installation in standard distribution boards.

## Long description

The ABB DS301CA-B16 is a high-performance RCBO (Residual Current Circuit Breaker with Overcurrent protection) designed to provide comprehensive electrical safety in a compact, single-module format. This device integrates both overload and short-circuit protection with residual current detection, ensuring reliable operation for single-phase electrical circuits. Engineered for precision and durability, it effectively monitors for sinusoidal alternating and direct pulsating earth fault currents, offering a robust solution for modern electrical distribution systems.
Advantages
The primary advantage of the ABB DS301CA-B16 is its space-saving design, which combines multiple protection functions into a single module width, allowing for more efficient use of space within distribution boards. Its Type A sensitivity ensures that it detects not only standard AC leakage currents but also pulsating DC components, which are increasingly common in modern household appliances. The device is built to high manufacturing standards, providing consistent performance and long-term reliability for both residential and commercial electrical installations.
Suitable for
Residential single-phase circuit protection
Commercial office electrical distribution
Protection of circuits with electronic equipment sensitive to pulsating DC
General lighting and power outlet circuits
Retrofitting existing distribution boards where space is limited
When it may not be suitable
This device is designed specifically for single-phase 230V systems and is not suitable for three-phase electrical installations. Furthermore, it should not be used in environments where the ambient temperature or environmental conditions exceed the specified IP20/IP40 protection ratings, such as areas with high moisture or excessive dust without appropriate enclosure protection.
Key specifications
Rated current: 16A
Configuration: 1P+N (Single pole plus switched neutral)
Sensitivity: 30mA
Type: A (AC and pulsating DC fault currents)
Voltage: 230V AC
Frequency: 50-60Hz
Breaking capacity: 6kA
Mounting: DIN rail (1 module width)
How to use
The ABB DS301CA-B16 must be installed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting onto a standard DIN rail 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, paying close attention to the neutral connection. Once installed, the device can be manually switched on or off using the front lever, and the integrated test button should be used periodically to verify the residual current protection functionality.
What to consider before purchase
Verify that the 16A rating matches the requirements of your specific circuit load.
Ensure your distribution board has sufficient DIN rail space for a 1-module device.
Confirm that the system voltage is 230V AC.
Check if Type A protection is required for your specific connected equipment.
Usage recommendations: It is recommended to perform a functional test of the residual current protection mechanism using the integrated test button at least every six months to ensure the device remains in optimal working condition.
