KSD314 Big Large Current 25A Automatic Reset Bimetal Disc Thermostat For Washing Machine

KSD314 series snap-action thermostat is a kind of hermetically sealed bimetal thermal protector(3/4" disc). Working under resistive load, it has high loading capacity, and its max current could reach 45A. This series is suitable for high-duty electric appliances as temperature control or overheat protection.

KSD314 thermostat is divided into 6 sub-series according to different structures and applications, they are KSD314-V, KSD314-Q, KSD314-R, KSD314-U, KSD314-T and KSD314-F.

Technical Parameter of Sub-Series

Resistance Between Terminals:Below 50 mΩ

Installation and Direction for Use

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.
If the thermostat is used to sense the temperature of liquids or steam, it is strongly recommended to adopt a version with stainless-steeled cup. Moreover, cautious measures should be taken to prevent liquids getting into/onto the thermostat’s insulation parts.
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.
