APPLICATION

Using characteristic
YKXD1 series circuit breaker  adport the hydraulic electronmagenetic theory. Used on the zero layor and sideface of combination shelf, integrated cabinet, frequency shift counter and lightning counter the in the contactor room of singal building as the equipment once or twice, overload and short circuit protection
YKXD1 series circuit breaker  slove the unstable factors of big discreteness of fuse current,aging and poor contact caused by oxidation.even in the extremly cold and hot enviroment it also can supply accurate and stable protection.
YKXD1 series circuit breaker vertically intalled special mounting plate.it is easy to install and replace
YKXD1 series circuit breaker when it trip the Actuator lever is in the middle position.it can indentify the either trip fault or manually trip
YKXD1 series circuit breaker can realize the concentrate alarm and bent alarm through alarm switch
YKXD1 series circuit breaker mounting plate and dust cover installed together it can avoid the unwanted movement function.
The certificate and standard
CRCC[2007]650 railway singal hydraulic electromegnetic circuit breaker telchnology
GB14048.2-2001 low voltage breaker equipement and control equiment low voltage circuit breaker
 
D1series also applied TB/T publiced by the railway department .VDE0642 and EN 60934

Attantion:
suggest to choose short delay curve 11
All the curve data is gotten at the temperature of 25 degree and havent added the time of load working trip time. vertically installed
When the the rated current is 105% it deosnt trip.when the rated current is above 130%,it should trip in the trip characteristic value
Base on 60HZ 1/2 cycle 8.33ms pulse.the capbility of minimum inrushed pluse is 12 times as rated current and when in high pulse it is 25 times as rated current .the trip time is in above .High pulse delay is used in power supply bulk capacitorand , load transformer and so on which has the big initial current in short time.
