DTE-450/3000protection relays tester
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.
