Short Circuit And Earth Fault Indicator Type EKL3B

Quick Details Model Number: EKL3B  Brand Name: Chaobo  Type: Panel Type  Usage: Ring Main Unit, Cable Distribution Box, Switch Cabinet IP Code: IP65(Fault Indicator Sensors) / IP55(Indicator Host)  Place of Origin: Zhejiang, China (Mainland) Lead time for sample: Within 5 daysMain Function: 1. Short circuit fault alarm indication: Short-circuit fault sensor installed on single phase cable, monitoring the current changes of the power supply line in time, when the current change value reach or exceed short circuit current action when the alarm set point (this value can be setting according to user requirements before producing),the short circuit fault sensor emit alarm signal, the signal through optical fiber sent to the indicator host, the corresponding fault indicator light flashing, Send out alarm indicator. 2. Earth fault alarm indication: earth fault sensors installed on the bifurcation unshielded part of three-phase cable, detection of three-phase cable of zero sequence current value, when its value reach or exceed the earth current action when the alarm set point(this value can be setting according to user requirements before producing), the earth fault sensor emit alarm signal,the signal through optical fiber sent to the indicator host, the earth fault indicator light flashing, Send out alarm indicator. 3. Battery low battery alarm indication: When the indicator host internal battery voltage drops to 2.5 V, generate alarm signal,to mention maintenance personnel change the battery, the alarm signal lasts about two months. Furthermore it equipped with an external power supply interface,can use an external power source.(Type B terminal 12 "-", 9 "+"; Type A terminal 8 "+", 9 "-" AC/DC5V-10V). 4. Remote alarm and reset: After the short circuit or earth fault occurred,
