PURPOSE: A coil temperature indicator of a contactor is provided to rapidly check the abnormal state of a system by monitoring and displaying a temperature state of a coil. CONSTITUTION: A power supply unit(200) supplies power to activate a coil part(210). A surge absorbing unit(230) removes a surge voltage from a voltage supplied from the power supply unit. A constant voltage unit(235) smoothes power supplied from the power supply unit to DC. A temperature sensor unit(225) senses a temperature of the coil part. A comparison determining unit(240) compares and determines the temperature sensed by the temperature sensor unit. [Reference numerals] (225) Temperature; (230) Surge absorbing unit; (235) Constant voltage unit; (240) Comparison determining unit; (245) Display unit |
