China JN22-40.5 Series Indoor HV Earthing Switch Manufacturer, Supplier, Factory

JN22-40.5 Series High Voltage Earthing Switch is an advanced level product with high tech parameters performance. After comprehensive evaluation, it conforms to GB1985 AC HV disconnect switch and earthing switch, applies to power system of 40.5kV and AC 50Hz. Can be used with KYN61-40.5 and other types high voltage switchgear, also play a protective role in the high-voltage electrical equipment overhaul.

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.

L1-63 residual current circuit breakers are protection equipment which must be used to protect human life against dangerous electric shocks or prevent the fires arising out of isolation mistakes thereby detecting isolation mistakes to occur within the plant in advance. Sigma residual current circuit breakers are produced with 2 and 4 poles in accordance with IEC EN 61008-1 standard and in compliance with CE norms under ISO 9001:2008 quality assurance system.

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.

Q3 Automatic Transfer Switch (hereinafter referred to as ATS), it is suitable for the power supply system of AC 50Hz, rated voltag f 400V, rated current of 63A and below. Choice and conversion between two power supply according to the needs. ATS have protection functions of overload, short circuit, under-voltage, but also have functions of fire, double breaking and output closing signal. Particularly applicable to the lighting lines in office buildings, shopping malls, banks, high-rise buildings and other places with needs of the fire.
