The Düwi 15140 screw-in miniature circuit breaker L-16A is an essential electrical protection device engineered to safeguard electrical circuits against overloads and short circuits. Designed for compatibility with traditional screw-in fuse sockets, this reliable component integrates seamlessly into existing residential and commercial electrical distribution systems, providing a dependable safeguard for your wiring and connected appliances.
Advantages
This miniature circuit breaker offers a practical and reusable alternative to traditional one-time fuses, eliminating the need for frequent replacements after an electrical fault occurs. Its robust construction ensures reliable performance over an extended operational lifespan. By offering precise current limitation, it helps protect electrical installations from thermal damage caused by excessive electrical loads. Installation is straightforward for qualified personnel, as it screws directly into standard fuse receptacles without requiring complex modifications to the existing fuse box infrastructure.
Suitable for
- Residential electrical distribution panels using screw-in fuse sockets
- Commercial buildings and office spaces with legacy fuse systems
- Overload and short-circuit protection for standard household circuits
- Workshops and outbuildings equipped with traditional threaded fuse bases
When it may not be suitable
This circuit breaker is not compatible with modern miniature circuit breaker panels that utilize DIN rail mounting systems instead of threaded screw-in receptacles. It is also unsuitable for circuits requiring a current rating other than 16 amperes.
Key specifications
- Rated current: 16A
- Mounting type: Screw-in design
- Protection function: Overload and short-circuit protection
- Brand: Düwi
How to use
Ensure the main power supply to the fuse box is completely switched off before attempting any installation or replacement work. Inspect the threaded fuse socket to verify it is clean, undamaged, and correctly rated for the device. Carefully screw the Düwi 15140 miniature circuit breaker clockwise into the socket until it is securely seated and makes firm electrical contact. Once installed, restore the power supply. In the event of a trip due to an overload or short circuit, disconnect the problematic appliance, allow the circuit breaker to cool briefly, and reset or screw it back into operational position depending on the specific trip mechanism.
What to consider before purchase
- Verify that your current electrical installation uses compatible screw-in fuse sockets
- Check that the 16A rating matches the electrical requirements of your circuit
- Ensure installation or replacement is performed in compliance with local electrical safety regulations
Usage recommendations: Regularly inspect screw-in circuit breakers to ensure secure seating within the fuse socket. Do not exceed the specified 16A current rating to prevent premature tripping and potential damage to the electrical circuit.
