Electric Technical parameters: Rated electrical performance: AC250V / 16A off temperature: 0 ℃ ~ 250 ℃ (according to user needs) Disconnect the temperature tolerance: ± 3 ℃; ± 5 ℃ ± 10 ℃-off temperature difference: 10 ~ 30 ℃ complex Temperature Tolerance: ± 5 ℃; ± 10 ℃ electrical strength: AC1500V lasted one minute without breakdown flashover. Insulation resistance: ≥5MΩ (DC 500V) Contact resistance: ≤50mΩ Fusing speed: F / fast KSD-301 series products are used as a bimetal thermostat temperature sensing components, electrical work, the bimetal in a free state , the contact is closed / off state, when the temperature reaches operating temperature, the bimetal thermal stress rapidly generated action, open / closed contact, off / on the circuit, and thus play a role in controlling the temperature. When the electrical cooling to reset temperature, contact automatically closed / open, return to normal working condition; manual reset thermostat is when disconnected or turned on, after the electrical cooling thermostat is not automatically reset need to manually reset the thermostat touch pressure will handle the contacts closed / open, this will make the thermostat recover before the next state to work. Main purpose: Widely used: water dispenser, water heaters ,, microwave, coffee maker, electric cooker, refrigerator, air conditioning, a plastic machine, office equipment, automotive seat heaters and other electric appliances. Features: This thermostat is a small temperature controller, fixed operating temperature performance, without adjustment, simply, reliable action, no arc, long life, low radio interference. The thermostat is a small temperature control and overheating protection; as Xiaoduwangui, electric open water bottles, coffee maker, electronic watt support, hot water bottle, water dispenser, hair dryer, vacuum cleaners, electric heaters, microwave ovens, irons, dry clothes dryers, motors and other electrical appliances. With stable performance, high accuracy, small size, light weight, high reliability, long life, worry about the radio characteristics of small dry. Note: 1, using the contact temperature installation, should be charged with snapping the metal to cover up the installation of surface equipment, to ensure that the temperature effect, should be coated with thermal grease or other similar properties in the heat transfer medium temperature sensing surface . 2, the installation can not cover up the top collapsed, loose or deformed, so as not to affect performance. 3, can not allow the liquid to penetrate the internal temperature, not cause the shell cracks, not free to change the shape of the external terminals. 4, the product is not greater than 5A current of the circuit used, should be selected cross-section of 0.5 5-1㎜2 copper wires; not more than 10A current in the circuit, chose copper wire cross-section 0.75-1.5㎜2 connection. 5, the product should be less than 90% relative humidity, ambient temperature below 40 ℃ ventilated, clean, dry, non-corrosive gases stored in the warehouse. KSD301 classification, can be divided according to the temperature, can also be classified according to the material, it can be divided in accordance with the installation. According to the nature of the action points: the action can be divided into normally open and normally-off operation.
