Dual-power automatic switching switch is a product developed by our company with the latest technology. It is suitable for dual-power automatic switching power supply system with AC 50Hz, rated working voltage 400V and rated current 1250 A. This product has the protection of overload, short circuit, over-voltage and short-phase. When the power supply fails, the switching device can complete the automatic switching between the common power supply and the standby power supply. It is widely used in hospitals, shopping malls, fire protection, banks, chemical industry, metallurgy, high-rise buildings and military facilities where power is not allowed to be cut off.
Control and protection switchgear is mainly used for switching on, carrying and breaking the current or voltage under normal conditions (including prescribed overload conditions) in power system, and also for switching on the current and voltage under abnormal conditions (such as short circuit, undervoltage, etc.) which are prescribed for carrying a certain time and breaking off. It realizes integrated and coordinated control and protection functions in a single-mechanism product. It can replace many traditional separation components and has the function of long-distance automatic control and local manpower control.
Surge protector is suitable for power supply system and can be used as equipotential connection when lightning strikes. Usually installed in the low-voltage main cabinet of the building’s entry line.
