DATA SHEET APLICACIONES TECNOLOGICAS IGA TEST series protectors cut off the power supply when they detect a permanent overvoltage (for example, a fault in the neutral), thus protecting the equipment installed downstream. To restore the main circuit breaker, it is necessary to reconnect the protective coils in advance using the RESET buttons. Reclosing will always be carried out from the most external coil to the one closest to the MCB. IGA TEST permanent overvoltage protectors can be used together with ATSUB-D transient overvoltage protectors. The integrated MCB is available for the most usual nominal currents: 6, 10, 16, 20, 25, 32, 40, 50 and 63 A. > INSTALLATION They must be installed in series with the low voltage line, between the power control circuit breaker (ICP) and the residual current device (ID). Installation should be carried out without power running through the line. The protective coils are to be installed between the lines connected to the residual current breaker and the neutral. The protector is formed by protective coils for permanent overvoltage linked to a miniature circuit breaker (MCB).
