DPR-03 relay is a three-phase (line to line) voltage protection relay designed to be used for over-voltage, under-voltage and phase rotation protection in distribution substations, generators, motors, transformers and capacitors in compensation systems. It offers adjustable over / under voltage limits together with adjustable trip and reset delays. The unit has also phase sequence protection. Both over voltage limit(Max) and under voltage limit(Min) 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 under voltage limit (L-L) Adjustable over voltage limit (L-L) Adjustable TRIP and RESET Delays Phase sequence protection Phase failure protection Overvoltage protection Insufficient supply protection 6A/277VAC relay output.
