KSD314-Q series thermostat has two operating temperatures, which have two functions: temperature control and temperature limit. The temperature control function is used for temperature control under normal conditions and can be reset. The corresponding operating temperature is called temperature control temperature. The temperature limit function is used for the cut-off protection during abnormal overheating and cannot be reset. The corresponding operating temperature is called the temperature limit temperature. Generally, the temperature limit temperature is higher than the temperature control temperature. This product is equivalent to a combination of KSD314-V and KSD314-N.
The product contact is single-pole single-throw (SPST), the shell is made of high-temperature resistant resin material, the temperature control temperature is up to 100C, and the temperature limit temperature is up to 140C. The pressure rating is basic insulation, and certain additional measures can be taken to achieve a reinforced insulation level. The standard load nature is purely resistive, providing micro-disconnection.

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. |
