In order to ensure personnel electrical safety, the output circuits are galvanically isolated from the power supply. The voltage on the DTE-20M output terminals is less than 7V with fully opened thyristor, that is favorable for the circuit breakers contacts in time of tripping, which wear-out is significantly reduced during multiple tests.
