DETALHES DO PRODUTO
Aierway ZW32-40.5 series outdoor high-voltage vacuum circuit breakers are used in three-phase power systems with AC 50Hz and rated voltage of 35kV, as a means of separating and combining load current, overload current and short-circuit current. The circuit breaker can be equipped with reclosing controller to identify the current characteristics and achieve multiple automatic reclosing, self-provided PT as a power source to become an intelligent circuit breaker with voltage and current signal output and can be controlled; by the electronic PT to provide power and can complete the overcurrent delay, inrush current delay, short-circuit quick-break three-stage composite protection.
