WTHB Fuse Type Switch Disconnector
The fuse type switch disconnector of the WTHB series is a type of switch device used to disconnect circuits and protect electrical equipment. This switching device combines the functions of a fuse and a knife switch, which can cut off current when needed and provide short circuit and overload protection.
The fuse type switch disconnector of the WTHB series typically consists of a detachable fuse and a switch with a knife switch mechanism. Fuses are used to disconnect circuits to prevent the current from exceeding the set value under overload or short circuit conditions. The switch is used to manually cut off the circuit.
This type of switching device is commonly used in low-voltage power systems, such as industrial and commercial buildings, distribution boards, etc. They can be used to control the power supply and power outage of electrical equipment, as well as protect equipment from overload and short circuit damage.
The fuse type switch disconnector of the WTHB series has reliable disconnection and protection functions, and is easy to install and operate. They usually comply with international standards and safety requirements, and play an important role in electrical systems. -
