China MPH Heat Shrink Junction Box Manufacturer, Supplier, Factory

JSZVR type voltage transformer of epoxy resin cast insulated and totally-enclosed structure is intended for power measurement, current monitoring and relay protection in the line of up to 12 kV and AC 50-60 Hz.
●It is applicable to air insulated switchgear
●It conforms to GB1207 and lEC60044-2 standards

RCBO ABDT-63 Circuit Breaker are intended for electric shock hazard protection in case of electric installation insulation failures, for preventing fires caused by earth current leakages, overload and short circuit protection.

XUCKY PV SPD surge protective device is applicable to the low-voltage standard IEC EN 50539-11, and is used to protect the DC system and other equipment from overvoltage and instantaneous overvoltage damage. When DC system experiences surge overvoltage due to lightning strikes or other reasons, the protector immediately conducts within nanosecond time, introducing surge overvoltage to the ground, thereby protecting the electrical equipment on the point network. DC surge protection device is a plug-in structure that can be quickly replaced after a module failure; After the lightning protection module fails, the color of the indicator window changes from green to red, and an alarm signal is sent to the remote alarm device connected to the remote signal terminal of the product.
