Product Description
Manual Reset Snap Action Bimetal Thermostat KSD308 16A 250V 90C Thermal Switch For High Power Electric Water Heater
Description
KSD306 and KSD308 series products belong to the manual reset type protection thermostat, for the double knife structure, safe and reliable, suitable for high-power electric water heater (especially storage type electric water heater) overheating protection. It uses the principle that the disc-shaped bimetal produces an instantaneous jump when the temperature reaches a certain value. Through the mechanism conversion, the two pairs of contacts are quickly separated, so that the two-phase circuit is disconnected at the same time, and the purpose of completely cutting off the power supply is achieved. When you want to switch on the power again, you need to press the reset lever.

Installation and use instructions
* Method of earth: By means of the metal cup of thermostat connected in the earthing metal part.
* The thermostat should work in environment with humidity not higher than 90%,free of caustic, flammable gas and conducting dust.
* When the thermostat is used to sense the temperature of solid items, its cover should be clung to the heating part of such items. Meanwhile, heat-conducting silicon grease, or other heat media of similar nature, should be applied to the cover’s surface.
* The top of the cup must not be pressed to sink, so as to avoid adverse effect on the thermostat’s temperature sensitivity or its other functions.
* Liquids must be kept out of the thermostat’s inner part! The base must avid any force that could lead to crack; it should be kept clear and away from the pollution of electric substance to prevent insulation weakening that leads to short-circuited damages.
* The terminals should be bent, or else, the reliability of electric connection will be influenced.
