REC4 is a 2-pole differential circuit breaker associated with a smart reclosing motor, for safe reclosing of the associated RCCB. A compact unit that is installed as an RCCB, removing the need for interconnections between the motor and the RCCB. Insulation reclosing mode is used to ensure high-sensitivity protection, meaning the unit only recloses when the defect which caused it to trip has disappeared. The unit has a locking system that determines operation in manual or automatic mode (reclosing enabled).
All electrical installations requiring full continuity of power in the event of unexpected situations, which cause the earth leakage relay to trip due to causes not attributable to the electrical insulation.
