1The mechanical thermostat can be fixed on DIN standard rails (DIN15, DIN32, DIN35). 2The control range is 0 to 60, this product has the characteristics of easy installation, small size, and long service life. 3It can automatically start electric heaters and fans, produce condensed water drops, maintain a good working environment, and protect components. 4Small mechanical temperature regulators are designed to control electric heaters or cooling fans in electric cabinets, which are accidents caused by temperature factors. 5It is widely used in communications, wind power generation, firefighting equipment, ships, petrochemicals, large factories, coastal factories, docks, water treatment facilities, equipment, etc. ----------------------- Item Type: Thermostat Material: ABS Model: KTO 011 Type: (Normally Closed), Used to Control the Heater Working Principle: Due to the Different Thermal Expansion Coefficients, When the Temperature of the Bimetallic Sheet Changes, the Thermal Expansion and Contraction Degrees of the Two Sides Are Different, So the Degree of Bending Changes at Different Temperatures. When the Temperature is Higher Than the Expansion Temperature of the Bimetal, the Contact Position of the Bimetal is Deformed and Disconnected, and the Circuit is Disconnected. When the Temperature is Lower Than the Expansion Temperature of the Bimetal, The Contact Position of the Bimetal is Restored to Its Original Shape and Closed, and the Circuit is Closed. The Thermostat is Divided into Two Types: Normally Open and Normally Closed Normally Closed: When the Temperature is Set, the Thermostat is in the Normally Closed State. When the Actual Ambient Temperature Drops to or Close to the Set Temperature, the Load Heating Will Be Started. Usually the Thermostat is in the Normally Closed State. When the Temperature is Greater Than the Set Temperature, the Load is Always in a Stopped State. Normally Open: When the Temperature is Set, the Thermostat is in the Normally Open State. When the Actual Ambient Temperature is Greater Than or Close to the Set Temperature, the Load Will Be Started to Dissipate Heat. Usually the Thermostat is in the Normally Open State. When the Temperature is Lower Than the Set Temperature, the Load is Always in a Shutdown State Switch Temperature Control: 7K (4K Tolerance) Sensing Element: Temperature Sensing Material Contact Type: Fast Action Contact Contact Resistance: 100,000 Cycles Switch Large Capacity: 250VAC, 10(2)A; 120VAC, 15(2)A, DC 30W EMC: Acc. to EN 55014-1-2, EN 61000-3-2, EN 61000-3-,3 Connection Method: 2.5mm Wire Installation Method: 35mm Din Rail Shell Material: Plastic Ul94 Standard V-0 Fire Rating, Light Grey Adjustment Range: 0 to 60 Installation Method: Any Operating/storage Temperature: -20 to +80 (-49 to +176) Protection Level: IP20 ----------------------- 1 x Thermostat
