RGU-10 MT Electronic earth leakage protection relay with self-reclosing system
GENERAL DESCRIPTION
- Device with programmable differential relay with self-reclosing system. Symbol in LCD.
- It has 2 independents outputs by relays. Trip and locked by reclosing.
- It has 1 input for external Trip/Reclose. This input is not opto - coupled.
- Mounting in Rail DIN 46277 (EN 50022) or panel 72x72 by mean accessory (M5ZZF1)
- Associated to a WG/WGS Series external , toroidal current transformer.
- It must be asociated to a MCB motorized with or without a trip coil.
- It verifies connection with differential transformer WG/WGS by means inductive test.
- Leakage detection and measurement is via calculating its true efective value (TRMS).
- Display settings values and instant residual current to its accociated units.
DESCRIPTION LED AND BUTTONS.
- Shows equipment status via a display and 2 LED.
- 5 button equipment setup and setting.
- 2 button equipment TEST and RESET.
INDICATION BY LED AND DISPLAY.
- TRIP RELAY. LED and display signals a change
of status by changing from green to red.l
Display event type messages or values.
- BETWEN RECLOSURES.
The yellow LED is blinking. Red Display shows the
tripp cause fluctuating with partial reclosures No
- LOCKED BY RECLOSURES.
The yellow LED is fixed. The equipment arrives al
maximun number of reclosures established by the
self-reclosing sequence. Red display shows the cause.
- No OF RECLOSURES. By short press on PROG the display shows the number of reclosures by
earth leakage, short ciruit-overload faults and total number. The partial number are floating pages
In these pages it can configure the self-reclosing sequence by press REC button.
RECLOSING THE EQUIPMENT.
- BY TRIP / LOCKED BY RECLOSURES
1. Automathic (earth leakage, short ciruit-overload faults or manual). Enabled.
2. Manual reclose by pushing button RESET
3. External reclose sytem by remote or communications signal. When it forces a trip by remote
signal, only it can reclose by another remote signal.
4. Manual reclose circuit breaker associated.
In the case 2 and 3 the all partial counters of reclosures returns to a zero.

- SELF-RECLOSING SYSTEM, REC. In reclosure partial numbers by press REC button we
configure the self-reclosing sequence referred at the page which it’s showing us. By default is
configured nº10 by earth leakage protection and nº5 by short-circuit/overload protection.

¡ IMPORTANT !
The relay only self-recloses before a trip by earth leakage, short-circuit/overload current fault. The Test (red button) only
verifies the relay trips the protection. It recloses only by manual pressing RESET button.
