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

Product Features:
The switch with half sealed structures is made up of two parts: Theseat and cover(the fuse holder). Through the window in the cover,it can observe the rated data of the fuse links and indicatorstatus. The switch should be matched with the appropriate size offuse links accordingly. DR1-160/1 is single-pole and DR1-160 isthree-pole, both can be matched with size 000 and 00 fuse links.DR1-250/1, DR1-400/1, DR630/1 are single-pole and DR1-250, DR1-400,DR1-630 are three-pole. They are matched with size 1, 2, 3fuselinks separately. The three-pole switch can be combined withthe single-pole version with the same size into four-poleswitch.
The switch has the features of small size, reliable operation,convenient installation and removal.
All of these products, except for conductive parts, all are thefinger-touch protection: IP20. Compliance with GB14048.3 andIEC/EN60947-3.
