DTE-450/3000 protection relays testing device

DTE-450/3000 protection relays testing device

Protection relays testing device DTE –450/3000 intended for:

·adjustment and testing of simple protection relays in places of their installation: at power plants, substations, industrial plants or in the laboratory

·adjustment and testing of electroautomatics elements (electromagnetic relays, contactors, motor starters, etc.)

·adjustment and testing of circuit breakers

DTE-450/3000 tester housed within a single enclosure, which creates additional convenience during use. It includes connecting wires and cables to connect testing objects.
