JJS-200

Application Field and Working Principle

The JJS-200 (hereinafter referred to as the product) is a fast acting fuses mounted in a single pole with a reliable and robust design. This product is often used to quickly stop the current flow when an overload or short circuit occurs due to its melting response time and a very fast resetting time. Thus, it can avoid costly damages caused by the surge current.

The product is suitable for use in a wide range of applications, including electric power systems, electronics equipments, and surge protection. It can also be used in many industrial and commercial sites such as airports, wind turbines, and hospitals. Furthermore, the product has been designed for ease of installation and a wide range of current ratings, up to 200A.

Product Features

• Rapid response time-Melts within 3 milliseconds
• Resets very quickly-Reboots within 100 μs
• It can withstand surge current even at the high temperature
• Easy installation-Compatible with a wide range of compact circuits
• Excellent performance at high current intensities-Supports up to 200A

Working Principle

The product utilizes a high-precision bimetallic element as a fuse. This element is in direct contact with the main fuse wire. When an overload or short circuit occurs, the element quickly melts and breaks the current flow in a very short time. The melting time is very fast and the resetting time is very short, ensuring a safe and reliable current flow.

The product uses a special ferrous enclosure for support. The ferrous enclosure provides a robust, fixed and secure support for the complete fuse unit, and allows for easy installation and removal. The product also uses an insulated, high temperature-resistant ceramic base for better heat dissipation and strength when the fuse is operating at high temperature.

Conclusion

The JJS-200 is a fast-acting fuse with robust design and excellent performance. It is suitable for a wide range of applications and can withstand surge currents even at high temperatures. Its fast melting response time and quick resetting time makes it a reliable choice in any situation. The product is easy to install and provides a reliable and secure support system.
