0697W4000-02 Application Field and Working Principle of Fuses

Fuses are electrical safety products widely used around the world. They are designed to eliminate the possibility of fires, electrocution, or other accidents from occurring due to the over-heating of electrical lines and components. This article describes the application field and working principle of the specific type of fuse, the 0697W 4000-02.

Application Field

The 0697W 4000-02 fuse is designed for use in medium and low voltage systems with a maximum voltage of 1,000V AC or 1,500V DC. This type of fuse is usually used in the business and industrial sectors for protecting electrical equipment from damages or over-current. It has also been tested to meet RoHS and UL requirements and is considered to be very reliable.

Working Principle

The 0697W 4000-02 fuse has a simple and straightforward working principle. It is designed with an internal heating strip that melts when exposed to an abnormally high current. This causes the contacts within the fuse to disconnect the electrical circuit, effectively cutting off the power to the line and protecting the equipment from damages caused by the overload.The fuse can also be triggered by abnormally high voltage in the circuit. Instead of melting, the internal heating strip will expand, causing the contacts to break, thus disconnecting the circuit. This type of fuse has a voltage tolerance of up to 1,500V, meaning it can withstand surges up to this volt.

Conclusion

The 0697W 4000-02 fuse is a reliable and cost-effective solution for protecting electrical equipment in low and medium-voltage systems. It has an internal heating strip that melts when exposed to an abnormally high current, and can also be triggered by high voltage surges. This type of fuse has been tested to meet RoHS and UL standards, and is widely used in the business and industrial sectors.
