Self-reclosing overload and earth leakage protection Earth leakage protection and self-reclosing RCCB with Self-reclosing system Self-reclosing earth leakage relay Description . Features REC2 is a 2 or 4-pole earth leakage switch associated to a compact motor and control set that enables the automatic and safe re-closure of the installation, provided that the leakage is not permanent. The earth leakage switch is reclosed auto-matically, in accordance with the work mode selected (switch on the front): O Time sequence mode: after a switch trip, REC2 will make 6 reclosing attempts, with a...
