Product Description:
DR1 series of fuse-switch-disconnector is the newest developing from various products combination of products, it combines fusing protection, isolation and switching in order to make the distribution unit smaller, more reasonable and attractive.
For DR1series of fuse-switch-disconnector, the rated insulation voltage is up to AC 50Hz 800V, the rated working voltage up to 690V and the rated working current up to 630A.

Product Features:
The switch with half sealed structures is made up of two parts: The seat and cover(the fuse holder). Through the window in the cover, it can observe the rated data of the fuse links and indicator status. The switch should be matched with the appropriate size of fuse links accordingly.
