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.

Technical Requirements of KSD308 Thermostat

1)rated voltage and current: AC250/1.5A-20A

2)open temperature range: 115-120C

3)electrical strength
A: between the shell and the wiring terminal, it can withstand AC1500V/ 0.5ma and does not break down or flash for 1min.
B: after disconnection, it can withstand AC800V/ 0.5ma, 3S without breakdown and flicker.

4)Insulation resistance: under normal≥100MΩ

5)contact resistance: ≤50M Ω
