3kv-36kv Zinc Oxide Lightning Arrester is a device to protect electrical equipment from overvoltage transients caused by external (lightning) or internal (switching) events. Also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS), this class of device is used to protect equipment in power transmission and distribution systems. (For consumer equipment protection, different products called surge protectors are used.) The energy criterion for various insulation material can be compared by impulse ratio, the surge arrester should have a low impulse ratio, so that a surge incident on the surge arrester may be bypassed, to the ground instead of passing through the apparatus.

XUCKY Three phase adjustable voltage protection device,a new generation of home appliance protectors, suitable for houses, hotels, buildings, school dormitories, etc., to protect the electrical safety of appliances and other loads, to prevent damage to the load caused by too high or too low mains power.

CJ12 AC Contactor is mainly used for electric equipment of metallurgy, electric power and hoister. It is suitable for the circuit of AC 50/60Hz, the voltage up to 380V, current up to 600A for remove making and breaking circuit, and frequency starting, stopping and inverse AC motor. The products comply with IEC60947-4.

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.

XUCKY NDM1 Moulded Case Circuit Breaker (NDM1, hereinafter referred to as MCCB), is new circuit breakers which have been designed and developed by the company using international advanced technology. The circuit breakers are of the following characteristics: compact size, high breaking capacity, short arc-over distance and shakeproof, is ideal products applied on land or ships. The rated insulation voltage of the circuit breaker is 800V (500V for NDM1-63), it is suitable for the distribution network of AC 50Hz / 60Hz, rated working voltage of 690V and rated current of 1250A, to distribute power and protect circuit and power equipment from being damaged caused by overload , short-circuit, under-voltage and other fault. Also for protection infrequent conversion of the circuits and infrequent start of motor and overload, short circuit, under voltage.

ZN12-12 40.5 series indoor high voltage vacuum circuit breaker is a 3-phase AC 50Hz 12kV/40.5KV indoor switch equipment.
