Electrical, Specialty Fuses can provide a variety of electrical protection solutions for different applications. The 0RLS070.V fuse is one such protection device. This article will discuss the application field and working principle of the 0RLS070.V fuse.

Application Field

The 0RLS070.V fuse is designed for medium-voltage switching and protection applications in industrial, commercial, and institutional facilities. It can be used for main lug/load center switchboards, panel boards, switchgear, and motor control centers. The melting curve of the fuse ensures the fuse will not trip too early or too late in order to avoid downtime or repair cost.

The 0RLS070.V is designed to handle a maximum voltage of 600 VAC and an interrupting capacity of 40 kA at 600 VAC. It is suitable for use in circuits with a maximum amperage of 70 amperes. The 0RLS070.V also provides safe and reliable disconnection of primary sources, such as service entrance and transformer lines up to 600 VAC.

Working Principle

The 0RLS070.V fuse consists of two main parts: a fuse element and a fuse holder. The fuse element is placed in series within an electrical circuit, and consists of a cylindrical copper structure with a ceramic core. The core contains a special material, zinc oxide, which has a higher electrical resistance than copper. When the electrical current passing through the fuse element reaches its maximum rating, the material in the core absorbs the heat generated by the current and begins to melt. When the heat absorbed surpasses the melting point of the material, the fuse element melts, breaking the circuit. This process is known as “overcurrent protection.”

The fuse holder is responsible for containing the fuse element so that it can be easily installed within the electrical circuit. It also helps the fuse element to quickly break the circuit when too much current passes through it. The fuse holder is typically made of plastic, but can also be made of other durable materials.

Conclusion

In summary, the 0RLS070.V fuse is designed for medium-voltage switching and protection applications in industrial, commercial, and institutional facilities. It can handle a maximum voltage of 600 VAC and an interrupting capacity of 40 kA at 600 VAC. The 0RLS070.V is composed of a fuse element and a fuse holder, and its working principle relies on the melting point of its core material. This ensures that the circuit is safely disconnected when the current surpasses the maximum rating.
