The switch is made up of two parts: the seat and the cover  (melt-loading device), three-phase and sealed. The front operation can observe the rated data of the fuse links and indicator status. The switch is molded designed.
Installation: MRO·H2(DR2)-160  (50mm in width), can be directly installed on 100mm busbar through the output  line. It has up output  line and down output line. Three phases make and break simultaneously. This switch is suitable  for 000, 00  fuse. MRO·H2(DR2)-400 (102mm in width), can be directly installed on 185mm busbar through the output line, it can also be installed on the supporter by two φ12×18 installation hole. Both of the installation methods have up output line and down output line, and three phases make and break simultaneously. This switch is suitable for NH1, NH2 fuses.
MRO·H2(DR2)-630 (102mm in width), can be directly installed on 185mm busbar  through  the  input  line, it can also be installed on the  supporter by two φ12×18 installation hole. Both of the installation methods have up output line  and  down output  line,  and three phases make and break separately. This switch is suitable for NH3 fuses. MRO·H2(DR2)-160/L (52mm  in width), can be directly installed on 185mm busbar  through the input line. Both of the installation methods have up output  line  and down output  line,  and three phases make and break  separately. This switch is suitable for 000 and 00 fuses.The switch has the feature of small volume, reliable performance, convenient fuse install and removal, small-required manual operation power.

MRO.H2(DR2) series  fuse disconnecting  switch are mainly used  in circuit with high short-circuit current and motor circuit as power switch, disconnecting switch or emergency switch and for AC protection.Rated  insulation  voltage up  to AC 50Hz 1000V; Rated working voltage up to 690V; Rated working current up to 630A.Rated limiting short-circuit is 100kA at the voltage of 500V and 50kA at 690V. Rated short-time withstand current (valid) : 20Ith/1S. The fusedisconnecting  switch  complies with GB14048.3 and IEC/EN60947-3 .
