1. General Features

This Earth Leakage Detector (GD16-L05A, GD16-L05R) is used protect to leakage fault of

less than AC600V line.

Operation produces earth fault to ZCT Primary line flowing earth current do detection through

ZCT and is digital arithmetic type earth leakage detector that is used to check fault's extension

breeding alarm.

Features

 16 Circuit Digital Total arithmetric type Earth Leakage Detector
 The Earth Leakage Detector and ZCT are convenient handling through compatibility.
 Display the measured values and leakage line ( 7-Segment )
 Each circuit setting : Current detect sensitivity
 Malfunction Prevented through over input protection and filter circuit
 Inspect the equipment of leakage circuit conveniently, because can be select the restore

method.

 Can control for more Buzzer installation or Display through output contact.

(GD16-L05R Type only)

 Convenience of the ZCT selection by various ZCT types for equipment capacity
