WRU-10. Earth leakage relay with built-in transformer (type A)
|
|
|
|
|
 |
|
Electronic relay with earth leakage protection with built-in 28 mm transformer, constituting one unit.
Type A high-insulation, with high frequency current filter and high insulation. Measurement in true root mean square (TRMS).
Display with LED and display:
- Earth leakage protection parameters.
- Protection trip current.
- Protection status messages, etc.
Unit with three programmable contact output relays, one switched and two simple. The main relay is for the protection provided by the contact or trigger coil of the automatic switch while the other two are for the pre-alarm.
- It also has a voltage-free input for external triggering and resetting.
- Assembly on DIN Rail 46277 (EN 50022)
- Reduced three-module size.
- Connection by pluggable terminals.
