Electronic Motor Protection Relays by Western Products

We specialize in providing Motor Protection Relays with Delta/star Converter for Energy Saving (DSR Series), which is highly reliable, efficient and well known for its excellent performance & durability. These are highly applicable for 3 phase induction motors up to 2500 Amp and equipped with Micro-computer & Smart logic current sensing algorithm. This further results in energy saving and precise motor protection on partial loading by automatic change over from Delta to Star & Star to Delta. Our range of Motor Protection Relays with Delta/star Converter for Energy Saving (DSR Series) is specially designed to provide protection to electrical motor in industrial applications against over current / under current, locked rotor, frequent start/stop, ingle phasing, phase reversal, earth leakage and thermal overload. Some of the quality attributes of our range is enlisted below: Current base Smart logic Motor monitoring algorithm for protection & Energy Saving on partial loading Easily programmable protection parameters & trip delay settings Instantaneous response to abnormal supply or load conditions 7 segment LED display for monitoring all three phase currents as well as tripping annunciation Site selectable trip class for customized trip characteristics based on motor type & nature of application Menu driven user interface with 3 Key & 7 segment LED display Displays and records trip events for enhanced fault analysis option available for RS 485 connectivity for interfacing with PC or DCS Wide operating voltage range (Control supply) 90 V to 270 V AC (other options available on request).
