The Disconnector Fuse Group is the ideal solution for high-current connections and disconnections. Its modular design makes it easy to assemble according to your needs, while the integral structural design ensures stability. The spring energy storage mechanism allows for quick and easy connections and disconnections, even at high speeds.
HGLR-63~400 disconnector fuse group adopts modular design structure, which can be assembled freely according to customer requirements.
HGLR-630 adopts integral structural design to ensure the stability of product performance due to its high current.
The operating mechanism adopts a spring energy storage mechanism. When the product is connected and disconnected, the spring can be released instantly to realize rapid connection and disconnection (13.8 M / s), which is independent of the speed of the operating handle and greatly improves the ability to extinguish the arc.
The Disconnector Fuse Group is a safe and easy way to disconnect your electrical circuit. Made of high-quality glass fiber reinforced unsaturated polyester resin, this switch has a visual shield for easy disassembly and replacement of the fuse link. The Disconnector Fuse Group also has self-cleaning contacts for a reliable connection, and over-current and short-circuit safety protection functions.
Suitable for multiple low-voltage distribution cabinets, details include: GGD low-voltage fixed switchgear, GCK withdrawable low-voltage switchgear, MNS low-voltage withdrawable switchgear, XL-21 power cabinet, etc

Normal Working and Installation Conditions
The maximum ambient air temperature shall not exceed +40℃, with a minimum of -5℃. The average temperature inside the building should not exceed +35℃ within a 24 hour period. The installation site should not be located more than 2000m above sea level.
When the maximum temperature is above 40℃, the relative humidity of the air should not exceed 50%. However, at lower temperatures, higher relative humidity is allowed; for example, 90% at 20℃. If condensation due to temperature changes should occur, special measures should be put in place.
The pollution level of the surrounding environment is level 3.isolator switch on or off
The switch shall be installed in a place without significant shaking, shock vibration and rain and snow invasion. At the same time, the installation place shall be free of explosive dangerous medium, and the medium shall be free of gas and dust sufficient to corrode metal and damage insulation.
