General
YCQ9E series automatic transfer switch, rated working curent 16A to 630A,to be used in pow- er systems for ensuring the continuity of the supply, by transfering a load between two power supply sources. The switch has three working posions of “Main ( I ) cosing”, “Standby ( II )
closing” and “Double-of (0)”, which can be used for fire-fighting linkage and infrequent con-
necion and disconnecion of power supply systems. Mainly used in hospitals, shopping malls, banks, chemical industy, metalurgy, high-rise buildings, military facilities and fire-fighting occa- sions where power failure is not allowed.
Standards: IEC 60947-6-1

YCW3 series air circuit breakerthereinafter calledACB)issuitable for the circuitof AC50Hz/60Hz with ratedservicevoltage 400V,690V and ratedservicecurrent between200A and 6300A.Itis mainly used to distribute electric energy and protect circuitsand electric equipment against over-load,under-voltage,short-circuit and singlephase earthingfault.
YCM3 Series moulded case circuit breaker,is new products,with small compact, modular,high break,double breakpoints,zero arcing,green environmen protection.Suitable for AC 50Hz,60Hz,rated operating voltage 690V and below, rated current 12.5A to 1600A distribution network,used to distribute electrical energy and protection lines and power supply equipment from overload,short circuit and undervoltage failure hazards.It can also be used as a non-frequent conversion of the line under normal conditions and in the infrequent start of the motor.
General
YCM7, YCM7RT, YCM7T/A, YCM7RE series circuit breaker is a new generation of breaker. This breaker is applied for the distribution network of AC 50Hz, rated insulation voltage 800V, rated working current up to 800A, which is for electric energy distribution, circuit protection, protection power supply facility from destroying by the fault of overloading, short circuit and undervoltage, meanwhile it is also used for protection from unfrequent starting, over loading, short circuit and undervoltage of the motor.
YCM8N Series circuit breakers are developed according to domestic and international market demand, as well as similar products.
Its rated insulation voltage is up to 1000V, suitable for AC 50-60Hz distribution network circuit whose rated operation voltage is up to 690V, rated operation current from 10A to 630A. It can distribute power, protect the circuit and power supply devices from the damage of overload,short circuit and under voltage, etc.
This series of circuit breaker is featured as high breaking capacity and short arcing. It can be installed vertically (namely vertical installation) and also installed horizontally (namely horizontal installation).
Standards: IEC60947-2.
This series of Automatic transfer switch is suitable for AC 50Hz/60Hz, rated working voltage 230V/400V and below power distribution and control circuit.The current up to 63A. It is mainly used as the main switch of terminal electrical appliances, and can also be used to control various types of motors, low-power electrical appliances,lighting and other places.
