Schneider Electric A9D20610 Residual Current Circuit Breaker with Overcurrent Protection 2P 10A 30mA Type AC

The Schneider Electric A9D20610 is a high-quality residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive safety for electrical circuits. This 2-pole device combines the functions of a miniature circuit breaker and a residual current device in a single compact unit, effectively protecting against short circuits, overloads, and earth leakage currents. It is designed for standard electrical distribution systems, ensuring reliable operation and enhanced safety for both residential and commercial environments.

The primary advantage of this RCBO is its ability to integrate two critical protective functions into one space-saving module, which simplifies installation and optimizes space within electrical distribution boards. By detecting both overcurrent conditions and leakage faults, it significantly reduces the risk of electrical fires and protects users from accidental contact with live parts. The robust construction and precise engineering ensure long-term durability and consistent performance under standard operating conditions.

Suitable for

• Residential electrical distribution boards
• Commercial building circuit protection
• Standard lighting and socket circuits
• Protection against earth leakage and overcurrent in indoor installations

When it may not be suitable

This device is designed for AC type leakage detection and may not be suitable for circuits involving complex electronic equipment that generates DC components or high-frequency interference. It is not intended for use in environments with extreme moisture, corrosive atmospheres, or outdoor locations without appropriate protective enclosures.

Key specifications

• Number of poles: 2
• Rated current: 10A
• Residual current sensitivity: 30mA
• Type: AC
• Function: Overcurrent and earth leakage protection

How to use

The device should be installed by a qualified electrician in accordance with local electrical regulations. It is mounted onto a standard DIN rail within a distribution board. Ensure that the supply cables are correctly connected to the input terminals and the load cables to the output terminals, following the wiring diagram provided on the device housing. After installation, the functionality should be verified using the integrated test button to ensure the tripping mechanism operates correctly.

What to consider before purchase

• Verify that the 10A rating matches the requirements of your specific circuit load.
• Ensure the 30mA sensitivity is appropriate for the intended level of human protection.
• Check that your distribution board has sufficient DIN rail space for a 2-pole module.
• Confirm that the AC type is compatible with the connected electrical appliances.

Usage recommendations

Regularly test the device using the test button at least every six months to ensure the mechanical tripping mechanism remains functional and reliable.
