​
Protection
-
Over/Under current
-
Locked Rotor
​
Auxiliary
-
Self-diagnostics
​
Main Features
-
MCU based digital control : optimized protection
-
Compact size,Practical simple application
-
Protection : Over current/Under current, Phase Loss ,Locked rotor
-
Protection for Phase loss and Locked rotor is executed based on over current
-
-
Possible to check actual current and trip state based on LED indication
-
-
3 phase load protection through 2 CT
-
To cover wide and precise current range for the protection
-
10 Type
-
Definite T-I: 0.3A∼12A(0.3~6A for external CT)
-
Matched with external CT :1~600A, secondary rating of external CT is 5A
-
-
60 Type
-
Definite T-I: 2A∼60A
-
-
-
Trip cause indication by LED
-
Control power is loaded : Green
-
Normal operation : Red
-
Trip is happened : Yellow
-
-
Convenient functional selection by DIP SW
-
N type : trip output(95-96,97-98) is energized in case control power is loaded
-
R type : trip output(95-96,97-98) is not energized in case control power is loaded
-
trip output is not responsed for selection of DIP SW in case normal operation is processed
-
-
RP ON : able state to protect reverse phase protection
-
RP OFF : disable state to protect reverse phase protection
-
-
Reset after tripped
-
Manual : press “RESET” SW
-
Electrical : control power(A1-A2) off → possible to make remote control by power switch with remote distance
-
-
Self-diagnostic function : “TEST” SW
