Knife fuses

Knife fuse links are widely used in industry. Their task is to protect power installations against the effects of short circuits and overloads. Therefore, they are considered universal fuses with reliable operation.

Knife fuses:

characteristic

Knife fuses have electrical parameters and dimensions in accordance with with the requirements of standards adapted to electrics in the industrial sector. These are the standards: PN - 93 / E-06160, PN-IEC-269, VDE 0636. Fuses are mounted in fuse bases with an insulating holder. The most important parameter to consider when selecting fuses is the rated voltage. Therefore, when checking products from the manufacturer nh Hager , one should follow this determinant. Light fuses do not take up much space and are therefore very practical. Their visual setting is at a high level, which means that there is no risk of not recognizing what the signaling suggests. Maximum cable protection is ensured due to the high short-circuit breaking capacity for all fuse sizes and rated currents. The high short-circuit current limitation capability is impressive. Manufacturers also emphasize the stability of current-time characteristics and full selectivity of operation, enabling compatible interaction with overcurrent circuit breakers. As fuses of this type do not take up much space, they also reduce the costs of the installation itself. Therefore, for example, they work well as protection of overhead lines , and at the same time their cost-effectiveness is emphasized. The main role of blade fuses is to protect electrical installations against the effects of short circuits and overloads. In addition, they also protect motors with a low nominal current. They work both as transformer protection and semiconductor protection , which allows their versatile use.

Knife fuses: advantages of using

Knife fuses have many advantages related to their direct application. Silver-plated knife contacts result in low power losses, which once again indicates economic use. To further reduce the cost of the installation, compact inserts can be used. Due to the stability of the current-time characteristics and the full selectivity of operation, knife fuses work very well under certain conditions. Knife contacts can be made of copper or brass, and are additionally protected with a layer of silver. Copper with the addition of silver has an excellent effect on the performance shown during operation.

The presented knife-type fuses are a type of electrical protection in which the electrical circuit is interrupted by the melting of one of the elements. The greater the current, the less time it will take for the fuse to operate. Naturally, after a single operation, the fuse should be replaced with a new one. The main element is the topic. Melting it down will ignite the arc, which will still be sustained by the flowing emergency current. For the arc to extinguish and open the circuit, the current must drop below the threshold value.

The advantages of using individual knife fuses mean that these elements can be used in many ways. This is one of the reasons why they are widely used in industry. If someone cares about choosing the right element, he should check the leading parameters. It is crucial to adjust the fuse to the system that is to protect against short circuit or overload. The general characteristics indicate how to use fuses. Their use depends on it, and the protection of power installations will remain at a high level. Whether it's to protect cables or other components, knife fuses will prove to be reliable.
