Introduction

The LR254003CR fuseholder is a device used to securely hold a fuse in place while providing electrical power and protection. It is used to protect electrical circuits from receiving too much voltage. The device is made up of a holder frame and base, along with a contact arm that moves up and down when the fuse is inserted. When the current is too high, the contact arm will shut off the flow of current, thus protecting the circuit.

Application Field

The LR254003CR fuseholder is used mainly in automotive applications, such as replacing blown fuses. It can also be used in any location that requires a fuseholder, such as in air conditioners, electronics, and power supplies. This type of fuseholder is also suitable for industrial and residential applications.

Advantages

The LR254003CR fuseholder provides easy installation, with adjustable mounting holes for flexibility. It is also flame retardant, and can withstand temperatures up to 125°C. It also has a high current rating (20A) and is shock and vibration-resistant. The fuseholder also offers protection against overcurrent, providing reliable protection for your system.

Working Principle

The working principle of the LR254003CR fuseholder is quite simple. When a fuse is inserted into the holder, an electrical connection is made and a contact arm is energized. When the current is too high, the contact arm will disconnect the connection, thus breaking the flow of current and protecting the circuit. If the current is reduced, the contact arm will reset itself, allowing the current to flow again.

Conclusion

The LR254003CR fuseholder is a reliable and durable device. It is designed to provide safe and reliable electrical protection for any application, whether automotive, industrial or residential. It is easy to install, flame retardant and shock-resistant, and provides reliable current protection.
