RGU-10C MT Electronic earth leakage protection relay with self-reclosing system
For instance, RGU-10C MT supplied by 110 V a.c.
GENERAL DESCRIPTION
DESCRIPTION LED AND BUTTONS.
- 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
/
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
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.
- Shows equipment status via a display and 2 LED.
- 5 button equipment setup and setting.
- 2 button equipment TEST and RESET.

LED and display signals a change
of status by changing from green to red.l
Display event type messages or values.
The yellow LED is blinking. Red Display shows the
tripp cause fluctuating with partial reclosures No
.
The yellow LED is fixed. The equipment arrives al
maximun number of reclosures established by the
self-reclosing sequence. Red display shows the cause.
-
By short press on
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
button.

1. Automathic (earth leakage, short ciruit-overload faults or manual).
Enabled.
2. Manual reclose by pushing button
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.

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.
