DIGITAL Over Voltage & Under Voltage Relay [59/27]▶ CHARACTERISTICSUp to now OVR and UVR relays were separately setandoperated,
but now they are compacted in one relay unit.
Therefore, it is very convenient for handling, too.
As assembled with state of the art and multifunction, it is most
suitable and applicable for protective coordination.
Volt meter being installed, it can be used for measuring.
Electronic indicator can accurately detect troubles, and surely
indicate electrical troubles.

DIGITAL Over Current & Earth Fault Relay [50/51 X 3] [50N/51N]
▶ CHARACTERISTICS
Easy coordination between wiring and receving point of OCR with
only 1set of relay.
With LCD display showing all information about the state of setting
and input current value of each phase, also, LED lights indicating
the running state.
Selective operating time consists of definite time, normal inverse time,
very inverse time, and extremely inverse time.
Detecting faults correctly at the time of short circuit as well.
The relay was electronically structured, therefore it works semi-permanently.
