Circuit breaker is a mechanical device designed to close or open contacts member thus closing or opening of an electrical circuit under normal or abnormal conditions. Circuit breakers are usually employed for the protection of electrical circuits, they are equipped with a
3 way switch is a lighting control procedure that is very much useful to turn “off” or turn “on” a lighting fixture from two different locations. Since there are 3 conductors connecting the switches in a 3 way light switch wiring we
The Hall effect was discovered 18 years before the discovery of electrons i.e. in 1879 by Edwin Herbert Hall. This achievement happened when he was working on his doctoral degree at the Johns Hopkins University in Baltimore, Maryland, USA. What is Hall
Circuit Breaker is one of the most important equipment in the power distribution system. This is because of the function of the equipment itself which is, the ability to open a circuit or to break the circuit during maintenance work or when
To compare the application of medium-voltage circuit breakers and of fused contactors, we must understand the basic characteristics of each switching technology. The below table shows the major characteristics of medium-voltage circuit breakers and medium-voltage fused contactors that influence the application. Of
A contactor is an electrically controlled switch used for switching an electrical power circuit , similar to a relay except with higher current ratings. Contactor is in fact an electromechanical switch. Low-voltage Contactor is an electrically controlled switch used for switching an
