Function
1. Personnel and fire protection
2. Cable and line protection against overload and short-circuits.
Selection
1. I∆n ≤ 30 mA: additional protection in the case of direct contact.
2. I∆n ≤300 mA: preventative fire protection in the case of ground fault currents.
3. AC class – Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase.
General
YCM3 Series moulded case circuit breaker,is new products,with small compact,modular,high break,double breakpoints,zero arcing,green environmentalprotection.Suitable for AC 50Hz,60Hz,rated operating voltage 690V and below,rated current 12.5A to 1600A distribution network,used to distribute electricalenergy and protection lines and power supply equipment from overload,shortcircuit and undervoltage failure hazards.It can also be used as a non-frequentconversion of the line under normal conditions and in the infrequent start of themotor.
FN7-12R(L)AC MV load switch used in 50Hz,12kV three phase AC power system
FN7-12R(L)series vacum circuit breaker is indoor high voltage switch-gearwith rated voltage 12kV,three-phase AC 50Hz,which is developed by introducing from Switzerland,ABB corporation technology and analyzing domestic professiondevelopment condition,productivity development manufacture product.The overaltructure of this product is formed with theswitch mainbody and operating device,uses the compound insulation structure,does not have the pollution and the explosionhazard,and the insulation level is high.This operating device of the series product is for the spring loaded type,can use theelectrically operated operation,also can use the manualoperationc Standard:IEC 60265-1,IEC62271-105.
The Signal Lamp is applicable to circuit with rated voltage 230V~and frequency 50/60Hz for visual indication and signaling.
