2. PRODUCT DESCRIPTION
REC4 is a 2 or 4-pole type A RCCB linked to a smart reclosing motor, which enables safe reclosing of
the corresponding RCCB.
In the REC4-2P model, the insulation reclosing mode is used for high sensitivity protection, so that
the device only recloses when the fault that caused tripping has disappeared. The rest of the models
implement the timed reclosing mode to ensure power supply continuity.
The device features:
- 2 LED indication.
- Automatic reclosing by insulation or Time, depending on the model (Table 3 and Tabla 4).
- Protection cover for the reclosing system.
- Mode selection switch to select between Manual and Automatic operating mode and physi-
cally lock the reclosing device.
- 1 indication output, to indicate the blocking of the device due to the maximum number of
reconnections (Model REC4-C).

3. DEVICE INSTALLATION
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 neces-
sary personal protective equipment and pay attention to the various warnings indicated
in this instruction manual.
The REC4 device must be installed by authorised and qualified 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 REC4 is a device specifically designed to be installed in electric panels or enclosures, with DIN rail
fixing 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 REC4 downwards until it is secured to the lower section of the DIN rail.
3.- Make sure that it has been secured on the rail.

3.3.- CONNECTION
The REC4 must be connected to an installation protected with fuses suitable for its power supply range
and consumption.
Note: Cross-section of the cable: 16 - 25mm2
Terminals, opening covers or removing elements can expose parts that are hazardous
to the touch while the device is powered
If the REC4 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.
