What is MCB? MCB or Miniature Circuit Breakers is a mechanical switching device which is capable of making, carrying and breaking currents under normal circuit conditions and also making, carrying for a specified time and automatically breaking currents under specified abnormal circuit conditions such as those of short circuit. So we can say that MCB… Read More »
What is an ELCB? An Earth Leakage Circuit Breaker (ELCB) is a safety device used in electrical installations with high earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use… Read More »
It is well known that Circuit Breakers are devices which are used to break a circuit continuity and restore it again when required. Normally these are known as switching devices that can be activated manually or automatically to control the electrical power systems. In case of short circuiting or leakage of the larger amount of… Read More »
