Protective disconnecting device (PDD)
PDD is designed to ensure quality control of grounding in the used electric system throughout the entire time of operation of electrical equipment. PDD compares the potential difference between the primary and reference earths. In case of a potential difference of more than 25V, an audible alarm is activated and the power supply is automatically switched off. There are variants of PDD for internal and external mounting.
