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. CATALOG NUMBER MRO . H 1 - / MRO with size 1, 2, 3 fuselinks separately. The three-pole switch can be combined with the single-pole version with the same size into four-pole switch.
B. The switch has the features of small size, reliable operation, Fuse- Switch- Disconnector Conventional free air thermal current (A)
Pole convenient installation and removal.
C. All of these products, except for conductive parts, all are the finger-touch protection: IP20. Compliance with GB14048.3 and IEClEN60947-3. Design code 1-single poles none-three poles 4-four poles
