Selective Differential Switch 25A 300mA 4P VД1-63S IEK for Circuit Protection

The automatic switches, controlled by differential current, without built-in overcurrent protection, functionally independent of the voltage of the network, household or similar application with time delay of disconnection type VD1-63S are designed for automatic disconnection of power supply, in case of occurrence of differential leakage currents, in single-phase and three-phase electrical networks of alternating current rated voltage up to 400V. VD1-63S are designed for installation in low-voltage complex input and distribution devices operated in residential, public and industrial facilities, as well as construction sites.
