250V AC 40A 95C Celsius NC Temperature Control KSD Bimetal Thermostat KSD307
Products Description
KSD307 series temperature controller is a bimetallic sheet contact temperature sensing relay with a fully closed shell. According to the principle of thermal expansion and cold contraction, the metal sheet will be bent so as to achieve the maximum jump and switch in the pre-set temperature range, which plays an important role in the safety protection of electrical appliances. The disconnect temperature and reset temperature can be made according to customers’ requirements.
KSD307 series of 1/2 "(13mm) self-hold bimetallic disc thermostat provides time-tested reliability in a wide range of applications. The self-hold construction incorporates a PTC heater that is located throughout the electrical position of the contacts. When the contacts are closed, the PTC heater is shunt and therefore not energized. When the contacts are open, the PTC heater is connected to the load in series and energized to keep the temperature sensitive bimetal in an actuated state. To reset the temperature sensing control, power to the device must be cycled off to allow sufficient time for the component to cool down to a temperature below the bimetal switch reset point. KDS307 has a stable and reliable working temperature. It can be used repeatedly and is suitable for high reliability requirements of electrical safety protection.
