Mini manual motor starters, also known as manual motor protectors or motor circuit protectors, are compact electrical devices that provide overload and short-circuit protection for electric motors. They are typically used in small machines, appliances, and equipment that require limited power and control.
Mini manual motor starters consist of a thermal overload relay, a magnetic contactor, and a manual disconnect switch, all housed in a single enclosure. The thermal overload relay is designed to protect the motor against overheating and damage due to overloads or phase failures, while the magnetic contactor provides remote control of the motor. The manual disconnect switch allows for easy on/off control of the motor.
