GENERAL DESCRIPTION

- Device with programmable differential relay with self-reclosing system. Symbol
- 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
- Leakage detection and measurement is via calculating its true efective value (TRMS).
- Display settings values and instant residual current to its accociated units.

SELF-RECLOSING SYSTEM

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
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

RECLOSING THE EQUIPMENT.

- BY TRIP LOCKED BY RECLOSURES /
1. Automathic (earth leakage, short ciruit-overload faults or manual).
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.
