The 63A/100A Electronic Type Automatic Changeover Switch is designed to provide reliable and uninterrupted power to essential single-phase loads by automatically selecting the optimal power supply. It features over-voltage and under-voltage protection, along with a voltage display for monitoring. The switch ensures a seamless transition between power sources when one becomes faulty or experiences voltage irregularities, cutting off power instantaneously to protect electrical equipment. Additionally, the priority power supply can be set, and the switch will revert to it once normal voltage is restored.
