CIRCUTOR’s after-sales service. 2�- PRODUCT DESCRIPTION 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 fitted with automatic re- closing, 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.
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 sup- ply 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.

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 posi- tion, to disable the unit’s automatic reclosing device. ( Figure 4 The RCCB must be reclosed manually.
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.
