Earth Leakage Relays
| 
Description
Variable Earth Leakage Relays in compact 35mm din rail mounting cases for use on 3 phase electrical systems.
Application
To monitor earth leakage current and to operate an associated relay at a preset current. May be used to shut down a system or operate an alarm under fault conditions.
