OVERVIEW
DCELU32714A
DC Earth Leakage Detection Unit
The DCELU32714A is a DC earth leakage detection unit designed to monitor railway and industrial electrical systems for earth fault conditions. It continuously measures current imbalance across monitored supply conductors to identify potential earth leakage and insulation failures.
Featuring a latching alarm relay, reverse polarity protection and immunity to supply interruptions of up to 10 ms, the DCELU32714A provides reliable fault indication in demanding railway environments. It is also mechanically and electrically interchangeable with the DCELRH-100-100-465-3.
