Three Phase Digital Direct On Line Starter for any three phase motor up to 7.5 HP. Inbuilt Low/High voltages cut off, single phasing up to motor terminal and electronic overload protection is provided. Additional facility for duty cycle timer is provided. Once starter is switched on by pushbutton, it automatically switches ON and OFF motor depending on duty cycle timing. Manual switch is not provided.
There is simply no better way to provide ultimate protection to three-phase pumping systems than by adding a prime Electric state-of-the-art digital panel. It is designed to protect Three-phase pumps by monitoring current, voltage using integrated current transformers. A face mounted digital real-time display provides current and voltage reading.
- Electronic pushbuttons and fault indicating panel.
- Electronic Overload Protection calibrated with high accuracy and with inverse time current characteristics.
- Inbuilt digital current sensing single phasing protects motor against single phasing upto motor terminal.
- Unbalance current ckt. provides protection against unbalance supply voltage.
- Low / High voltage indication cum protection against extremely low and high voltage with hysteresis gape.
