168.6785.4402 application field and working principle

168.6785.4402 is a kind of mountable fuse, widely used in wind energy control system, Renewable energy system, PV system, MV system, Power system and Telecom system. It is a high-speed interrupting small size fuse.

It features high breaking capacity in a compact size. The working principle of the fuse is to react to an over-current situation such as a short-circuit or overload and break the circuit, thus protecting other components in the circuit. The fuse consists of four main components, the body, the fuse element, the connection and the housing.

The body is the fuse housings which acts as a holder for the fuse element. The fuse element is a metal wire or strip in the form of a coil, usually made of copper or silver. The connection is where the fuse links to the system. The housing encloses the fuse element and protects it from the surrounding environment. It can also be used to fix the fuse to other components such as circuit boards.

When an over-current situation occurs, such as a short-circuit or overload, the fuse element heats up and melts, thus breaking the circuit and protecting the other components in the circuit from damage. After the fuse has broken, it needs to be replaced with a new one. This is because the fuse element has been destroyed and is no longer able to protect the circuit from further over-currents.

The 168.6785.4402 is a very reliable and cost effective way of protecting critical systems. It is often the better choice over circuit breakers as it is small in size, light in weight and does not require any additional wiring or components. In addition, it is very easy to install and replace.
