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
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.

ZW32-24 outdoor MV vacuum circuit breaker (Hereinafter referred to as the circuit breaker) is outdoor distribution equipment with rated voltage 24KV, three phase AC 50Hz. It is mainly used for breaking and closing the load current, overload current and short circuit current of power system. Applied to substation and industrial and mining enterprises in power system for protection and control use, more suitable for rural power grid and the frequent operation place.

1.To prevent electric shock,the power must be off when wiring isto be carried out

2.Wiring shall be arranged directly according to ports. Please confirm whether allconnections are correct.

3.Use drag steering.

4.To reduce electromagnetic interference to electrical wires,

equipment and wires shall be connected in suitable range with same size for shortest connection.

5.Wiring layout shall be away from any internal electromagnetic nterference source.

6.The cross section of wires connecting power must be 0.5mm2-2.5mm2(20-14AWG;75℃(min)).And the current load of the wires shall be 6A.

7.Copper wire (standard or single core cable)can be used.

8.Before testing the equipment,please test the voltage and confirm whether it isproper
