KSD306、 KSD306-BKSD308 ,,
,() 。 ,,, ,。 ,。 The series of KSD306、 KSD306-B and KSD308 that is of double-pole structure falls in the category of manual reset type thermal protector. The product series, safety and reliable, is used in high-duty electric water heater for overheating protection. When the instant snap of bimetal disc occurs at certain temperature, two contacts separate promptly by means of mechanical transition and simultaneously two-phase circuit disconnects in order to completely cut off power supply. Pressing reset lever will restore the power supply.

/INSTALLATION AND DIRECTION FOR USE
:。 Method of earth: By means of the metal cup of thermostat connected in the earthing metal part.
90%、、。 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.
