Products/DSP-CTM-10Z7
Main Feature
- ▪ Panel Flush Mounting Type
- ▪ Access restricted to authorized operator : Password
- ▪ Compact size,Multi function
- – Protection : Over current/Under current/Phase loss/Reverse phase/Locked rotor/Current unbalance,Ground fault
- – Indication :Current/L1-L2- L3 , earth current, Load Factor[operating/preset “oc”],Alarm ,Trip,Accumulated working time[AWT]
- ▪ 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: current(L1,L2,L3),earth current, 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)
- ▪ High sensitive level and wide range for ground fault protection :30mA∼2A/Zero-phase sequence current
- ▪ 4∼20mA DC Output for current loop communication
- ▪ 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
