Application
JR28 series thermal overload relay are suitable foroverload and phase-failure protection of AC motors with frequency of 50/60Hzvoltage up to 690V,current up to 0.1-630A under 8-hoursdutyor uninterrupted duty.
Functions provided by these relays,are phase-failure protection,ON/OFF indication,temperature compensation,andmanual/automatic reset.
International Standard:IEC 60947-4-1The relays can bemounted onto contactorsor installed as single units

1.  YCB3000  series  frequency  converter  is  a  general-purpose  high-performance current vector frequency converter, which is mainly used to control and adjust the speed  and  torque  of  three-phase  AC  asynchronous   motors.  It  adopts   high- performance vector control technology, low-speed and high-torque output, and has  the  advantages  of  good  dynamic  characteristics,  super  overload  capacity, stable   performance,   powerful    protection   function,   simple    human-machine interface, and easy operation.

2.  It can  be used for driving of weaving, papermaking, wire drawing, machine tool,packaging, food, fan, water pump and various automatic production equipment.

General
The variable cross-section melt made of pure silver sheet (or silver wire winding)is soldered with low-temperature tin and packaged in afusion tube made of high- strength porcelain.The fusion tube is flled with chemically treated and specially processed Process-treated high-purity quartz sand isused as the arc-extinguishing medium,and the two ends of the melt are firmly electrically connected with the contacts byelectric welding
