China VCB Manufacturer, Supplier, Factory

China XUCKY Electric customized JR20 Thermal Overload Relays are suitable for circuits with AC 50Hz, voltages up to 660V, and currents up to 630A, to protect against overload, phase failure and three phase unbalance of AC motor.

The PV combiner box is a wiring device in the photovoltaic power generation system that ensures the orderly connection and confluence function of photovoltaic modules. This device can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and reduce the range of power outage in case of photovoltaic system failure. The combiner box means that the user can connect a certain number of photovoltaic cells with the same specification in series to form a photovoltaic tandem, and then connect several photovoltaic tandem to the photovoltaic combiner box in parallel. After converging in the photovoltaic combiner box, through the controller, DC distribution cabinet, Solar inverter, and AC distribution cabinet, a complete photovoltaic power generation system can be formed to achieve grid connection with the mains.

XUCKY's AFDD-32 Series Arc Fault Protectors arc-protected type B + residual current operated circuit breaker (Af-rcbo-RRB- protects against arc, residual current, over-under voltage, overload transients, etc., it is recommended to use in the places with dense personnel and inflammable materials, such as home, school, nursing home, hotel, historic buildings and so on.

High quality customized products DZ47-125 Miniature Circuit Breaker from China suppliers and manufacturers, XUCKY Electric has been specialized in Modular Electrical Terminal Equipment for many years. Our products have a good price advantage and cover most of the South America, Middle East, Africa, Southeast Asia markets. We look forward to becoming your long-term partner in China.

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.

HG2B In-line Fuse Switch Disconnector is suitable for AC rated voltage 660V and below, AC 160A~630A, rated AC frequency 50Hz. With load operation, the first current transformer and bar switch integration, with the advantages of convenient adjustment of upper-lower inlet-outlet, three-phase separate breaking, three phase simultaneous breaking and others, widely used in complete sets of products and imported box substation.
