H2 Fuse Switch Disconnector
![Home Home](../images/home.jpg)
Applications
- H2 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.
- Rated insulation voltage up to AC 50Hz 1000V; Rated working voltage up to 690V; Rated working current up to 630A; Rated short-time withstand current (valid) : 20Ith/1S.
- The fuse disconnecting switch complies with GB14048.3 and IEC/EN60947-3 .
Design Features
- The switch with half sealed structures is made up of two parts: the seat and cover (fuse holder).
- Through the window in the cover, it can observe the rated data of the fuse links and indicator status.
- Installation: The switch molded designed.
- H2-160(50mm in width), can be directly installed on 100mm bus bar through the input line. There are two type versions available: up output line and down output line, three phases make and break simultaneously, suitable for NH000 and NH00 fuse links.
- H2-250(102mm in width) can be directly installed on 185mm bus bar though the input line, it also can be installed on the supporter by two 12x18 installation holes. There are two types version available: up output line and down output line, three phases make and break simultaneously or separately, suitable for NH1 fuse links.
- H2-400(102mm in width) can be directly installed on 185mm bus bar though the input line, it also can be installed on the supporter by two 12x18 installation holes. There are two types version available: up output line and down output line, three phases make and break simultaneously or separately, suitable for NH1, NH2 fuse links.
- H2-600(102mm in width) can be directly installed on 185mm bus bar though the input line, it also can be installed on the supporter by two 12x18 installation holes. There are two types version available: up output line and down output line, three phases make and break simultaneously or separately, suitable for NH3 fuse links.
- H2-160/L(52mm in width) can be directly installed on 185mm bus bar though the input line, it also can be installed on the supporter by two 12x18 installation holes. There are two types version available: up output line and down output line, three phases make and break simultaneously or separately, suitable for NH000 and NH00 fuse links.
- The switch has the features of small size, reliable operation, convenient installation and removal.
- All of these products, except for conductive parts all are the finger-touch protection: IP20.
- Compliance with GB14048.3 and IEC/EN60947-3.
