Drop out fuses are suitable for power systems with a frequency of 50Hz and a rated voltage of 35KV and below, installed on the high voltage side of distribution transformers or on the main lines of distribution. The main functions include areas with low requirements for protection performance, which can be used in conjunction with isolation switches to replace automatic air switches; It can also be used in conjunction with load switches to replace expensive circuit breakers. It also has short-circuit protection, overload and isolation circuits.
