subject: Avoid Surges Using Circuit Breakers And Contactors [print this page] It is not an unknown fat that electrical surges are potent reasons behind buidings engulfing in fire. Therefore, be it a office building, residential property, factory or institution; proper care should be taken to keep the electricity flow under control. This is only possible by installing electricity controlling units.
A contactor is an electrical switch mainly used to switch a power circuit. This unit is used to control electric motors, heating and lighting units and capacitor banks. But it doesn't mean that it can interrupt a short circuit. Speaking about a contactor it comes in various shapes and sizes and usually have three parts; a contact, an electromagnet and an enclosure. The contact is the current carrying portion comprising power and auxiliary contact and contact spring.
The electromagnet generates a force to close the contacts when needed. The enclosure carries the contacts and electromagnet within. This enclosure is usually made of insulating materials like thermosetting plastics, Bakellite and other fabrics so as to safeguard humans from electrical shocks. There are a wide variety of contactors available as per their ratings. This rating is implemented on the basis of their load capacity, life cycle,voltage and maximum fault withstanding capability.
Now to talk about a Circuit breaker, it is an equipment to safeguard a circuit from electrical surges. This unit automatically shuts itself off, when it detects any overload condition to discontinue the flow. It usually operates like a fuse, but unlike a fuse, it can be reset to resume the electricity flow. This way it will not only save the household appliances from getting damaged but also the electrical circuits that often catch fire due to these surges.
Installing a circuit breaker is a tough task, hence better be left to the electrical experts. This equipment usually comes in various shapes, sizes and ratings. Obviously, this rating is based on the voltage carrying capacity of the breaker. These days, people using costly home appliances are advised to install this electrical breakers in order to safeguard themselves from getting crushed under huge repairing bills.
Studies have showed that surges are also responsible in generating heavy electric bills capable of burning a large hole in your pocket. So if you really want to avoid all thee circumstances, go get hold of these units from a reliale dealer. For this you can run a quick check online, to locate some dealers of branded and trustworthy electrical products. For more information - http://coronadobreakers.com/
