QLT electrical components Germany QLT model QLT price

QLT electrical components refer to switching devices capable of closing, carrying, and breaking current under normal circuit conditions, and capable of closing, carrying, and breaking current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague; generally, equipment above 3kV is referred to as high-voltage electrical apparatus. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. They can automatically cut off the circuit when serious faults such as overload, short circuit, or undervoltage occur.
