REC4 The REC4 allows one mode of automatic reclosing: - Reclosing by insulation, the device does not reclose until the leakage has disap- peared. 4�4�2�1�- Reclosing by insulation Following a time delay after a disconnection due to an RCCB trip, the REC4 makes a measure- ment to check whether there is a leakage current.
REC4 5�- MAINTENANCE The RCCB must be checked frequently. Test sequence ( Figure 10 1�- Press the TEST (T) key. 2�- Check that the RCCB jumps to OFF position. TEST Figure 10: RCCB Test Sequence� In the event of a Test sequence failure, contact the after-sales service. Instruction Manual...
