KSD314R & KSD314-R-C series are single-pole single-throw (SPST) manual reset type thermostat (contact is normally closed), and the housing is made of high temperature resistant resin material with a maximum operating temperature of 140C. The pressure rating is basic insulation. After certain additional measures, the reinforced insulation level can be achieved. The standard load property is pure resistance.
KSD314-R provides a conventional B-type micro-disconnection.
KSD314-R-C provides a more reliable E-type micro-disconnection, which is equivalent to the manual reset 1 of the UL standard. Its characteristic is that even if the reset mechanism is blocked, it will not prevent the thermostat from cutting off the circuit when it reaches the operating temperature, thus providing more reliable protection.

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. |
