China 12kV auto recloser - Rockwill Brand

RcwF type 12kV auto circuit recloser is designed for using voltage rating up to maximum 12kV level system.

In order to provide with a high reliable equipments, Rockwill's team increased the whole design schemas as below.

---------------------------------------------------

RcwF type 12kV auto circuit recloser is ANSI/IEC standardized plus design products which is equipped with one magnetic actuator mechanism, opening/Locking device (RCW type ACR without manual closing device) , 3 current sensors, max 6 voltage sensors, with more functional like protection curves + curves programble, coodination logics + logics  programble, programble communication protocols, PC software, APP control tool, etc... with RWK352 controller,....

---------------------------------------------------

RcwF type 12kV auto circuit recloser is a solid insulation reclosure without Sf6 GAS sealed. with high creepage design, higher insulation level, suit using for Maximum 12kV level sytem, BIL85kV.

It's vacuum interrupting technology, and IP55 IP protection class, it's a basic standard auto recloser...
