DATAKOM DPR-05 Motor Protection Controller, L-N, asymmetry

Unbalanced supply voltages cause often overheating, even damage in electric motors due to high circulating currents caused by asymmetrical voltages. DPR-05 relay is a three-phase (line to neutral) voltage asymmetry protection relay designed for electric motor protection. It offers adjustable asymmetry limit together with adjustable trip and reset delays. The unit has also phase sequence protection, phase failure and phase overvoltage protections. The asymmetry limit can be adjusted or disabled via trimmers on the front panel of the device. Delay timers are adjusted through related trimmers. FEATURES: DIN Rail mounted Adjustable asymmetry limit Adjustable TRIP and RESET Delays Phase sequence protection Phase failure protection Insufficient supply protection Overvoltage protection 6A/277VAC relay output.
