In the electrical system often there are failures and power surges. For long-term operation of the equipment, it is necessary to control the flow of energy consumed and regulate the incoming voltage to the electrical appliances. If the installation is incorrectly done in the electrical network or the insulation is broken, the resistance decreases or drops sharply. As a result, the current increases, which, when safe boundaries are exceeded, disables equipment and damages equipment and man. Therefore, to protect the devices you must use circuit breakers (fuse). Electrical fuse – a device with which help protect the electrical circuit from fire and overheating when current is overloaded. What does it consist of? The design is based on a fusible insert of constant or variable cross section. Insulating housing. Conclusions for fixing fuses and electrical circuit. Types of electrical fuses taking into account the principle of operation and the method of breaking the circuit: with a fusible insert – the leads are connected by a wire that is designed for a certain current, if this value is exceeded, the wire is broken. Self-healing – it is based on polymeric materials that have an acceptable AC current rate. When the supply of electricity exceeds a predetermined amount, the polymer is broken. After the current decreases, the circuit breaker recovers independently. Types of fuses depending on the structural assembly and material: glass and ceramic. If necessary, our professional managers will always help you choose and buy fuses. Product only from time-tested manufacturers. The circuit breaker is used for the safe operation of any equipment and apparatus that is connected to the electrical line. With its help, it is possible to avoid overheating of wires in the household electrical network and to protect devices from breakage during short circuits. It is necessary for the protection of transformers, electric lighting, heating and electric motors. In the online store of Eurocom Components, the price of a fuse depends on its type and purpose. You can order goods from a trusted manufacturer both in retail (from one) and wholesale (small or large). Delivery works throughout Ukraine.
