Star Delta Control Panels

                                

            Star Delta Control Panels are used for switching three-phase AC motors with very high inrush current. BOPARAI Star/D Control Panel connects the motor to the power supply with a starting delay of 10 to 45 sec through a voltage reduction method and increases the applied voltage in steps by changing star to delta position automatically. Designed with utmost precision, this product is perfectly meets the international quality standards. Manufactured using optimum quality raw material and the latest technology, this undergoes defined tests to make sure its flawless performance. Two types of Contactors are used in these panels. BOPARAI DC Contactors are of Air-Break type runs on 30 to 35 VDC. These contactors provides silent and chatter-free operations even at low voltages and BOPARAI AC Contactors are also of Air-Break type runs on 240 to 415 VAC. Parts of these contactors are easily accessible for cleaning, setting and replacement. . The contacts used in contactors are of high quality Silver Cadmium Oxide that provides long life and millions of trouble free operations.
