The Hager ADC966D is a high-quality 1+N pole residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive safety for electrical installations. This device combines the functions of a miniature circuit breaker and a residual current device in a single compact unit, effectively protecting circuits against both overloads and short circuits while simultaneously detecting leakage currents to prevent electric shock. It is designed for seamless integration into modern distribution boards, offering reliable performance for both residential and commercial electrical systems.
Advantages
The primary advantage of the Hager ADC966D lies in its space-saving design, which integrates two essential protection functions into one module, thereby optimizing space within the consumer unit. Its C-type tripping characteristic ensures stability against temporary current surges, making it ideal for circuits with inductive loads. Furthermore, the 30mA sensitivity provides a high level of personal protection against indirect contact, while the robust construction ensures long-term operational reliability and durability in various environmental conditions.
Suitable for
- Residential electrical distribution boards
- Commercial office lighting and power circuits
- Protection of individual final circuits
- General purpose electrical installations requiring combined overload and leakage protection
When it may not be suitable
This device is designed for AC type leakage currents and may not be suitable for installations where DC components are present in the leakage current, such as circuits connected to certain types of frequency converters or advanced electronic equipment. In such cases, an A-type or B-type RCBO would be required.
Key specifications
- Rated current: 16A
- Tripping characteristic: C-type
- Sensitivity: 30mA
- Leakage current type: AC
- Poles: 1+N
How to use
The Hager ADC966D must be installed by a qualified electrician in accordance with local electrical regulations. It is mounted onto a standard DIN rail within a distribution board. The supply cables are connected to the input terminals, and the load cables are connected to the output terminals, ensuring that the neutral conductor is correctly identified and connected to the designated N-terminal. Once installed, the device should be tested using the integrated test button to verify its mechanical operation.
What to consider before purchase
- Verify that the 16A rating matches the requirements of the circuit being protected.
- Ensure the distribution board has sufficient DIN rail space.
- Confirm that the AC type sensitivity is appropriate for the connected equipment.
- Check compatibility with existing busbar systems.
Usage recommendations
Regularly test the RCBO using the built-in test button at least every six months to ensure the tripping mechanism remains functional and to maintain optimal safety levels within your electrical installation.
