Earth fault monitoring relay KDZ-3JM

The KDZ-3JM earth fault measuring unit is to be used in automation and protection circuits as an element monitoring condition of insulation in both DC and AC circuits. The digital KDZ-3JM measuring unit is a device designed based on many years of experience in production and installation of switchgears, as well as state of the art trends and technical capabilities. KDZ-3JM is capable of signalling when alarm levels at the relays' contact couplings are exceeded and transmitting data to a monitoring system via Modbus RTU protocol.
