An EFS315 is an electrical specialty fuse designed and manufactured by a company called Capri Ltd. This fuse is mainly used to protect high voltage and low voltage electrical equipment from damage due to overload or short circuit conditions. This article will explain the application field and working principle of the EFS315.

Application field:

The EFS315 is a current limiting fuse designed for a variety of applications, such as motors, generators, transformers, cables, lighting systems and many others. It is suitable for both indoor and outdoor use.

The EFS315 is particularly beneficial in highly populated or hazardous areas, as it is capable of providing reliable protection against risk of instant-off due to short circuits.

The fuse is also recommended for use in transformer banks and substations, as it is designed to reduce the possibility of arcing and fire hazard, and greatly reduce the amount of damage which can be caused in case of a fault.

Working principle:

The EFS315 works by limiting the current to a safe level, thus preventing an overload or a short circuit condition from occurring. It is composed of 6 small breakers connected in series, each of which is provided with current limiting elements. When the current reaches a certain level, the elements heat up and cut off the current. This protects the electrical components and prevents further damage from occurring.

The design of the EFS315 also ensures that it automatically restarts when the fault current becomes too low. This allows the device to be used in applications where a normal fuse may not be suitable and provides the added benefit of increased reliability.

In addition to its safety and reliability features, the EFS315 also offers superior performance in terms of its time-current characteristics. This means that it can quickly cut off current within a very small time period, ensuring that the electrical equipment is effectively protected from damage.

Conclusion:

The EFS315 is a current limiting fuse designed for a variety of applications. It is particularly effective in areas which are highly populated or hazardous due to its ability to quickly cut off current. The fuse is composed of 6 breakers connected in series, each of which is provided with current limiting elements which heat up and cut off the current when the current reaches a certain level. The design of the fuse also ensures that it will automatically restart when the fault current becomes too low. This allows the device to be used in applications where a normal fuse may not be suitable and provides the added benefit of increased reliability.
