Product Description
MK1 Type Overtemperature Protection Triple Thermoswitch Thermal Protector 130C For Three Phase Motors
Description
MK Over temperature protection thermal switches(thermal protectors) are specially used for motor over-temperature protection.They are mainly applied to threephase motors. As the failures such as under-voltage,over-voltage and over-load can be reflected by the temperature of coil. MKthermal switchs are the ideal thermal sensing element to be used for motor protection.
Feature
MK over temperature thermal switchs(thermal protectors) are characterized by small size,flexiable movement and reliable performance.All of their indicators reach international advanced levels.
