For DDP65A, an electronic microprocessor that controls the pump is available for preventing dry runs, auto restart, and pump cycling.

Motor

The pump is powered by a single-phase motor with a thermal cutout for overload protection.
For direct connection to the mains power, a 5A fuse or MCB is used.
