Product Description
These series are one-pole normally close contactors; They are redesigned on the base of the military products of former Soviet Union. These series contactors are suitable in the appliance of programmed power supply systems, or uninterrupted power supply systems, fork trucks, motor vehicle, engine appliance etc. The design standards are followed by:
Standard YD/T512-92 < Technical Requirements for Telegraph Power Supply System >
Standard JB3974-198 < Basic Technical Requirements for DC Device of Battery Vehicle >
Standard ZBK63002-1998 < Basic Technical Requirements for Traction Device >
Standard GB14048.4-1993 < Low voltage Contactor and Motor-starter >
