Fuse Switch Disconnector 3p250A DIN Nh1 Mro H1-250230701012with Fuse Nt1 240103054

 PRODUCT FEATURES   

A. 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. MRO.Hl-16011 is single-pole and MRO.Hl-160 is three-pole, both can be matched with size 000 and 00 fuselinks. MRO.Hl-25011, MRO. Hl-40011, MRO.Hl-63011 are single-pole and MRO.Hl-250, MRO.H1400, MRO.Hl-630 are three-pole. They are matched
 
MRO.Hl 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 MRO.Hl series 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.
