←Functions and features→

1.high speedoptical switch: fast open and break in 3 ~ 6ms,ten times speed than the circuit breaker.

2.current limit switch:limit the 7.2~40.5Kv short circuit current peak value of the system to 15%~20% of the expected value.

3.High reliability:past the EMC.

4.Break linkage and actuating signal far propagation,avoid the open phase operation

5.Specialty current limiting in self-fuse mode.

6.Easy operation and installation: installation positions of unrestricted. Allow to stand alone outdoor or  indoor.

   also can be integrated in switch cabinet.

7.High Quanlity & Reasonable Price

8.Keep away the catastrophic short-circuit protection of the accident for the Power generation system , highly cost-effective.

9.Shells and shelves are made from tog grade Aluminium-zinc alloy coated steel sheet with 2mm thickness.
