Fuse Switch Disconnectors are widely used in various electrical systems, such as power grid distribution panel boxes, new energy systems, DC circuits, industrial control cabinets, photovoltaic equipment, industrial electric furnaces, combiner boxes, grid-connected cabinets, and even high current cabinets rated from 1000A to 2000A. These devices usually consist of a fuse and a disconnector, which are installed in the same frame and share a common operating mechanism. In this way, users can simultaneously realize the functions of fuses and disconnectors through the operating mechanism.
In power systems, disconnectors are mainly used to cut off circuits, isolate power supplies or loads to ensure safe inspection, maintenance, or troubleshooting. Fuses are used to automatically cut off circuits when circuits are overloaded or short-circuited, providing overload protection and short-circuit protection, thus protecting the safety of equipment and systems. Some models also feature excellent current limiting performance, which significantly enhances system safety.
Additionally, fuse switch disconnectors offer an obvious disconnection point, ensuring that the circuit is fully isolated during maintenance. They support load operation, allowing safe switching under load conditions. These products also undergo rigorous temperature rise tests to ensure stable performance under long-term operation. With a safety protection level of IP20, they are suitable for both professional and non-professional users.
Features:
1. Compact structure: The fuse and disconnector are integrated together to save space.
2. Convenient operation: The functions of fuses and disconnectors can be completed through one operating mechanism.
3. High safety: When a circuit fails, the fuse can quickly cut off the circuit to prevent the accident from expanding.
4. Isolation function: When inspection, maintenance, or troubleshooting is required, the power supply or load can be effectively isolated.
