JCY-1/2E

JCY-1/2E fuses are one of the most versatile and common specialty fuses used in many industries and applications. They are a UL recognized type and are suitable for use in many hazardous and safety interlock systems.

The JCY-1/2E fuse provides over-current protection for circuits carrying direct or alternating current. The fuse is designed to be used in applications with a voltage rating of up to 250 volts. It is an excellent choice for control systems, power supplies, and motor protection applications.

When an over-current condition is detected, the fuse element will melt, thus preventing further current flow. This provides a high degree of protection from over-current conditions, while still allowing for normal current flow when conditions are normal.

Working Principle

The JCY-1/2E fuse is a type of thermal-delay fuse. This means that it has a built-in delay feature which helps protect against nuisance tripping. The delay feature allows for a certain degree of over-current before the fuse element melts.

When normal current flows through the fuse element, it barely reaches the temperature limit that causes it to melt. When an over-current is detected, the time it takes for the fuse element to reach its melting temperature is delayed, allowing for a specific amount of over-current before the element melts.

Applications

The JCY-1/2E fuse is a very versatile and commonly used component in many industries and applications. The fuse is most commonly used for motor protection, control systems, power supplies, motor protection, digital systems, and other applications where over-current protection is required.

This fuse is also suitable for use in hazardous and safety interlock systems, such as those found in medical applications, industrial plants, and manufacturing environments. It is also very useful in applications where quick response time is necessary, such as in arc welding.
