5 Earth leakage protection and self-reclosing RCCB with Self-reclosing system REC2 Self-reclosing earth leakage relay Description REC2 is a 2 or 4-pole earth leakage switch associated to a compact motor and control set that enables the automatic and safe reclosure of the installation, provided that the leakage is not permanent. Output contact available in REC2C model Protection Class Measurement Sensitivity I Dn Delay Test Electromechanical, Class A Instantaneous value 30 ma or 300 ma (depending on the type) Fixed at 20 ms With built-in button The earth leakage switch is reclosed automatically, in accordance with the work mode selected (switch on the front): Time sequence mode: after a switch trip, REC2 will make 6 reclosing attempts, with a timer set at 10, 20, 30, 60, 120 and 600 s. If the set can not be reclosed, it will be blocked in a trip status until it is reset manually. Insulation monitoring mode: after the switch trip, REC2 repeats the previous sequence, but it measures the presence of leakage current in the installation before carrying out the reset. REC2 will only reclose when the insulation measurements are correct. There are LEDs on the front part of the control module to indicate the operation status: Manual or automatic reclosure Reclosure mode selected Reclosing status Lock status Drop-down window to activate/deactivate the automatic reclosure of the earth leakage switch.

19 Overcurrent and earth leakage protection and self-reclosing MCB MCB Series Circuit-Breaker Description MCB-P or MCB-T are circuit-breakers that combine the functions of a circuit breaker (overload and short-circuit protection) and those of a contactor on the same element. There are two options with MCB: Closed circuit-breaker: Allows remote control functions (contactor function). It can be disconnected and reconnected electrically with the adequate signal. Circuit-breaker opened by an overload or short-circuit trip or by manual disconnection: remote control reset is not allowed, only manually. The remote control function works on the same contacts as those of the circuit breaker, guaranteeing the disconnection in each case. The MCB-T type includes a remote control module with two auxiliary, potential free (three-wire) contacts that indicate the status of the MCB at the input of the remote control (contactor function) and/or the circuit breaker.
