## Long description

The Schneider Electric A9F03240 is a high-quality 2-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in both residential and commercial environments. This device is designed to detect and interrupt overcurrents, effectively safeguarding wiring and connected equipment from the risks associated with overloads and short circuits. With its robust construction and precise B-curve tripping characteristics, it offers a reliable solution for maintaining electrical safety and system integrity.
Advantages
This miniature circuit breaker stands out due to its precision engineering and adherence to strict safety standards. The B-curve tripping characteristic is specifically optimized for applications where low-level short-circuit currents might occur, providing a balanced response that prevents nuisance tripping while ensuring rapid disconnection during genuine faults. Its compact 2-pole design allows for efficient space utilization within standard distribution boards, making it an excellent choice for modern electrical installations where panel space is at a premium.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Protection of lighting circuits
General purpose electrical installations
This circuit breaker may not be suitable for applications requiring high-inrush current handling, such as large motor starting or heavy industrial machinery, where a C or D-curve breaker would be more appropriate. It is also intended for indoor use in controlled environments and should not be installed in locations exposed to moisture, dust, or extreme weather conditions without an appropriate protective enclosure.
Key specifications
Rated current: 40 A
Number of poles: 2
Tripping curve: B
Protection rating: IP20
Width: 36 mm
Depth: 78.5 mm
Height: 91 mm
How to use
The device is designed for mounting onto a standard DIN rail within a distribution board or consumer unit. Installation should be performed by a qualified electrician in accordance with local electrical codes and regulations. Ensure that the power supply is completely disconnected before attempting to install or replace the unit. The cables should be securely terminated into the terminals, ensuring that the connections are tight to prevent overheating. Once installed, the toggle switch allows for manual operation to connect or disconnect the circuit as needed.
What to consider before purchase
Verify that the 40 A rating matches the requirements of your specific circuit load.
Ensure the B-curve characteristic is compatible with the equipment being protected.
Confirm that your distribution board has sufficient DIN rail space for a 36 mm wide device.
Check that the installation environment meets the IP20 protection requirements.
Usage recommendations: Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform a functional test of the switching mechanism periodically to ensure smooth operation. Do not exceed the rated current capacity to avoid premature wear or nuisance tripping.
