Motor Protection Relays With Delta / Star Converter

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
