• Forced motor cooling structure. The motor cooling effect is high even when the motor part is not submerged in water, and the upper discharge structure makes it compact and easy to install in narrow spaces.
• Draining structure. By sealing the clearance of the core wire, in the unlikely event that the cable sheath is torn or the tip of the cable is submerged in water, water flowing through the small clearance of the core wire prevents water from flooding into the motor.
• Motor protection device. If the motor windings are abnormally heated or overcurrent flows for any reason, the built-in motor protection device detects this and automatically shuts off the electrical circuit to protect the motor.
