High-voltage capacitor protection fuses are crucial devices used to protect high-voltage capacitor banks. They come in various types, each differing in structure, working principle, and application scenarios.2025-11-08
O-type oil-immersed high breaking capacity high voltage current limiting fuse is a fuse with the advantages of good sealing, low power consumption, high breaking capacity, fast action and good protect2025-11-06
High-voltage current-limiting fuses are used to protect electrical equipment and connecting wires. They operate by heating the fuse element when the current flowing through the equipment exceeds the m2025-10-15
The fuse element in fuses and low-voltage load switches is connected in series with the circuit during operation, providing overload and short-circuit protection for wiring and electrical equipment. W2025-10-13
High-voltage fuses provide short-circuit protection. When a circuit or a device within it is overloaded or malfunctions, and the current in the circuit exceeds a specified value after a certain period of time, the fuse element heats up and melts, thereby disconnecting the circuit and interrupting the current, protecting the circuit or device.2025-09-29
