DREC-C is a 2 or 4-pole type A RCCB linked to a smart reclosing mo tor, which enables safe

reclosing of the corresponding RCCB.

In the DREC-C-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 imple ment 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).

-Protection cover for the reclosing system.

- Mode selection switch to select between Manual and Automatic operating mode and

physically lock the reclosing device.

ings indicated in this instruction manual.

The DREC-C device must be installed by authorised and qualied sta󰀨.

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

DREC-C

3.3.- CONNECTION

The DREC-C 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 DREC-C 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 sys-

tem for safety reasons And the AUTO and REC LEDs turn on to turn o󰀨 in a

few seconds. A manual reclosing of the system must be done on the panel with

voltage.
