KSD309 High Temperature Thermostat
The KSD309 series has the max. operating temperature (280°C) of snap-action thermostat. It suits for the high-temp. home appliances, such as oven, toaster, microwave oven etc. KSD309 series is divided into 2 sub-series: KSD309-A single body (temperature control), KSD309-C dual body (temperature control+protection).
KSD309 dual-temp.type bimetal thermostat has two pieces of bimetal discs with different preset temperature.It is equivalent to a combination of two SPST bimetal thermostat for temperature control and overheating protection.

INSTALLATION AND DIRECTION FOR USE
|Installation and use instructions:|
1. Grounding method: Connected to the grounding metal parts of the equipment through the metal casing of the thermostat.
2. The thermostat shall be operated in a general indoor environment where the relative humidity of the air is not more than 90%, no corrosive gas, no flammable gas and conductive dust.
3. When the temperature controller is in contact with the temperature, the cover should be placed close to the heat-generating part of the controlled appliance, and the thermal surface of the cover should be coated with thermal grease or other similar heat-conducting medium.
4. When the temperature controller is exposed to liquid or steam, it is recommended to use a stainless steel cover and a reliable leak-proof measure to prevent liquid from seeping into the insulation of the thermostat.
5. It is not possible to collapse or deform the top of the cover to avoid changes in operating temperature or other properties.
6. Do not allow liquid to penetrate inside the thermostat! The housing must be protected from excessive forces to prevent cracking; the housing should be kept clean to prevent contamination of conductive materials to prevent short-circuit breakdown due to reduced insulation.
7. The terminal cannot be bent during use, otherwise the reliability of the electrical connection will be affected.
