Three Phase Pool Pumps Motor Protector Thermal Switch Overload Protection Thermostat
The three -phase series thermostat is composed of glue wood shells, dynamic contacts, static tactics, electric heating wires, thermal dual metal discs, etc. When the electrical equipment fails, the current increases, when the rated current or the temperature exceeds the action temperature, the double (three) discs generated the heat expansion after generating heat. Overload or overheating or damage or burning. After the failure is eliminated, when the rated reset temperature is reduced, the protector is automatically reset, and the motor and other equipment will return to normal work.
