The operating mechanism is an acceleration mechanism with spring energy storage and instantaneous release. The instantaneous connection and disconnection of multi breakpoint contact structure is independent of the speed of the operating handle, which greatly improves various electrical and mechanical properties.
The disconnector fuse group can ensure the safe and reliable connection and disconnection of the circuit. It has reliable protection against overcurrent or short circuits. The disconnected state is clearly visible.
Fuse Switch Disconnector Structure Characteristics
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.
