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.
