2�- PRODUCT DESCRIPTION
REC 4
REC 4 is a self-reclosing RCCB according to the leakage current of the installation.
The device is designed for single-phase installations with 2 poles and is tted with automatic reclosing, which is activated following prior monitoring of the insulation, measuring the resistance
value downstream the RCCB in accordance with the temporisation indicated in the reclosing
table.
The device features:
- 2 LED indication.
- 30 mA sensitivity.
- Automatic reclosing by insulation.
- Protection cover for the reclosing system.
- Mode selection switch to select between Manual and Automatic operating mode and
physically lock the reclosing device.

3.1.- PRIOR RECOMMENDATIONS
In order to use the unit safely, it is critical that those who handle it follow the safety
measures set out in the standards of the country where it is being used, use the
necessary personal protective equipment and pay attention to the various warnings indicated in this instruction manual.
The REC 4 device must be installed by authorised and qualied staff.
Also, it is critical to keep the cables in perfect condition in order to avoid accidents, personal
injury and damage to installations.
The manufacturer of the device is not responsible for any damages resulting from failure by the
user or installer to heed the warnings and/or recommendations set out in this manual, nor for
damages resulting from the use of non-original products or accessories or those made by other
manufacturers.
If you detect any operational faults in the device or in its protection system, remove the device
from service.
This device has been designed for easy replacement in case of malfunction.
Disable the automatic reclosing function and disconnect the main protection device before handling active parts.
Please contact the after-sales service if you suspect that there is an operational
fault in the device.
3.2.- INSTALLATION
Do not use the device until it is fully installed.
The REC 4 is a device specically designed to be installed in electric panels or enclosures, with
DIN rail xing elements (IEC 60715).
To install the device on a DIN rail:
1�- Place the device at the top of the DIN rail.
2�- Swing the REC 4 downwards until it is secured to the lower section of the DIN rail.3�- Make sure that it has been secured on the rail.

REC 4
3.3.- CONNECTION
The REC 4 must be connected to an installation protected with fuses suitable for its power supply range and consumption.
In single-phase installations (phase and neutral, L and N), the supply cables are connected up
top and the cables from the protected loads are connected below.
The system will not work if they are wired in reverse order.

N
Figure 1: Connection diagram�
Note: Cross-section of the cable: 16 - 25mm
Terminals, opening covers or removing elements can expose parts that are
hazardous to the touch while the device is powered
If the REC 3 indicates a permanent failure (AUTO and REC LEDs are lit), you
must check the RCCB and the installation.
If the installation of the device is done with the RCCB in the OFF state, when
panel receives voltage the device will not activate the automatic reclosing system for safety reasons And the AUTO and REC LEDs turn on to turn off in a
few seconds. A manual reclosing of the system must be done on the panel with
voltage.

Once the device is installed you must carry out the following start-up sequence for it to work
properly.
4.1.- AUTOMATIC MODE
If the unit is going to operate in automatic mode, see Section “5.2.- AUTOMATIC”, the start-up
sequence is:
1�- Put the mode selector switch in Manual Mode (OFF).
2�- Lift the RCCB cover.
3�- Put the RCCB contact in ON mode.
4�- Lower the RCCB cover.
5�- Put the mode selector switch in Automatic Mode (ON).
Note: The switch has an M2 hole where you can attach a seal or a padlock to block access to
the RCCB and any other attempts at manual reclosing (Figure 3).

4.2.- MANUAL MODE
If the unit is going to operate in manual mode, see Section “5.1.- MANUAL”, the start-up sequence is:
1�- Put the mode selector switch in Manual Mode (OFF).
2�- Lift the RCCB cover.
3�- Put the RCCB contact in OFF mode.
4�- Lower the RCCB cover (optional).

5�- OPERATION
The device has two operating modes, manual and automatic, which can be selected using the
mode selector switch. (Figure 2).
5.1.- MANUAL
The REC 4 can operate in manual mode as if it were a standard RCCB.
To operate in this mode, the mode selector switch must be all the way to the top, in OFF position, to disable the unit’s automatic reclosing device. (Figure 4)
The RCCB must be reclosed manually.
The AUTO and REC LEDs are off.
Figure 4: REC 4 in manual mode, with mode selector switch at OFF�
5.2.- AUTOMATIC
To operate in Automatic mode the mode selector switch must be completely downward,in ON
position, to enable the device’s automatic reclosing system.(Figure 5)
The AUTO LED is constantly lit and the REC LED lights up based on the unit’s status.

REC 4
The REC 4 allows one mode of automatic reclosing:
- Reclosing by insulation, the device does not reclose until the leakage has disappeared.
5�2�1�- RECLOSING BY INSULATION
Following a time delay after a disconnection due to an RCCB trip, the REC 4 makes a measure-
ment to check whether there is a leakage current. If there is none it begins to reclose.
The REC 4 attempts a maximum of 3 measurements to check the leakage current; following
this the unit stays locked and does not automatically reclose.
If the time between a reclosure and the next trip is greater than the restart time, the reclosing
attempts start over at zero.
The delay and restart times depend on the number of attempts the reclosing device has made,
as shown in Table 3.

DelayRestartDelayRestartDelay Restart
<3 sec.10 sec.20 sec.20 sec.180 sec.60 sec.
The leakage current will be supervised by measuring the resistance downstream of the tripped
RCCB.
5�2�2�- RESTARTING THE RECLOSING SYSTEM METER
There are two ways to restart the internal reclosing system meter:
- Manually, by moving the mode selector switch from ON to OFF position and back to
ON.
- Automatically, when the restart time elapses after the last reclosing without tripping
again.
5�2�3�- RESTART IN CASE OF BLOCKING
In case of blocking of the device, the start-up sequence is:
1�- Check installation.
2�- Put the mode selector switch in Manual Mode (OFF).
3�- Lift the RCCB cover.
4�- Put the RCCB contact in ON mode.
5�- Lower the RCCB cover.
6�- Put the mode selector switch in Manual mode (ON).

Note : The switch has an M2 hole where you can attach a seal or a padlock to block access to
the RCCB and any other attempts at manual reclosing (Figure 3).
