The IGA TEST PLUS is a three-phase protector which is equipped with Miniature Circuit Breaker (MCB). The device is suitable for the detection of temporary overvoltage or undervoltage. It can also be used during failure on neutral operation, or in the shut down of power supply. As a result, it also provides protection to the components which are installed downstream.
The protective coil must be reconnected using the reset button to reestablish the device. It can be integrated with the ATSUB-D transient overvoltage protectors.
