Main Feature

• ▪ Panel Flush Mounting Type
• ▪ Access restricted to authorized operator : Password
• ▪ One Model is able to meet three kind of independent function
• – Voltage relay
• – Current relay
• – Power[Load/KW,Current]relay
• ▪ Compact size,Multi function
• – Protection :Over/Under Voltage/Over current/Under current/Phase loss/Reverse phase/Locked rotor/Current unbalance,Ground fault
• – Indication :Voltage, Load[KW]/Current,KWH, Earth current, AWT[Accumulated Working Time], Power Factor, Load Factor
• ▪ To show a trip cause and operational information in a character and/or a number : 5 Digit Window
• ▪ To indicate a necessasary information in every 3 sec: V,KW/Curr,KWH,Ec,AWT,Pf,Lf(Load factor)
• ▪ Convenient installation of ZCT to sense a zero-phase current for GF protection
• – Basic type : to use external ZCT(200mA/1.5mA)
• – Optional type : to use embedded ZCT (not suitable for external CT application)
• ▪ Current Loop Communication:Max current value in 3 phase is transformed into 20mA
• ▪ High sensitive level and wide range for ground fault protection :30mA∼5A/Zero-phase sequence current
• ▪ Alarm for disconnection with ZCT
• ▪ Alarm before Tripping by over current
• ▪ to check and/or to change preset value of each mode during the operation
• – Possible to check :press "SET" key
• – Possible to check and to change : firstly make "oPSEt" mode "on",then press "SET" key
• ▪ procedure after pressing "SET" key is same manner with usual preset job
• ▪ Various way to reset after trip: Manual,Electrical or Automatic /to response flexibly for applied sequence system
• ▪ Self-diagonostic test by one touch for "CLR" key
• ▪ History,Latest 8 trip events
