What is the working principle of MCCB?
What is the working principle of MCCB? MCCBs provides an instantaneous response to a short circuit fault, based on the principle of electromagnetism. The MCCB contains a solenoid coil which generates a small electromagnetic field when current passes through the MCCB. How many types of MCCB are there? There are five different types of MCCB: […]
