High Voltage 24kV Industrial Control Load Breaker Switch

Overview

       FKN12A-12D/T630-20 indoor high voltage pneumatic load switch-fuse combination (hereinafter referred to as FKN12A-12D load switch) is three-phase high voltage switchgear with rated voltage of 12kV and rated frequency of 50Hz, which is used for the separation and combination of load current, closed-loop current, no-load transformer and cable charging current. Turn off the short circuit current. Load switch equipped with ground switch can withstand short circuit current. FKRN12A-12D/T125-31.5 AC high voltage load switch-fuse combination is indoor high voltage switchgear combined with FN12A-12D load switch and Sport LAJ-2 (XRNT-10) high voltage current-limiting fuse. It can reliably turn on any current up to the short-circuit current, the load switch turns on the working current, the fuse turns on the short-circuit current, and the fuse turns on any overcurrent between the working current and the full short-circuit current. At the same time, the fuse switches off the load switch through its impinger.
