Moulded case circuit breaker (MCCB) is one of the most common low-voltage electrical components. It can make and break rated current reliably and cut off the current automatically when the current exceeds the trip setting.
Read MoreThe transformer iron heart magnetic flux is related to the exerted voltage. In the current, the excitation current does not increase as the load increases. Although the load is not saturated, the resistance loss of the coil will increase, exceeding the rated capacity due to the heat generated by the......
