Item Type: Mechanical Thermostat Material: ABS Model: ZR011 Type: Integrated Design of Normally Open and Normally Closed (Heating and Heat Dissipation) 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 Control7K4K tolerance Sensing ComponentTemperature Sensing Material Contact TypeQuick Action Contact Contact Resistance10m Service Life100,000 Cycles Switch Large Capacity250VAC, 10(2)A; 15(2)A; DC 30W Electro M agnetic CompatibilityAcc. to EN 55014-1-2, EN 61000-3-2, EN 61000-3-,3 Wiring2.5mm Lead Installation Method35mm DIN Rail Shell MaterialPlastic UL94 Standard V-0 Fire Rating, Light Grey Adjustment Range:0C to 60C Installation MethodArbitrary Operating/Storage Temperature-20 to +80 (-49 to +176) Protection LevelIP20 Package List 1 x Mechanical Thermostat 1 x English User Manual 1This thermostat can be fixed on DIN standard rail, integrated design of normally open and normally closed, dual purpose of heating and cooling. 2The temperature control range is 0 to 60. This controller has the characteristics of easy installation, small size, long service life, etc. 3Can automatically start electric heaters and fans, produce condensed water drops, maintain a good working environment, and protect components. 4Temperature regulators are designed to control electric heaters or cooling fans in electric cabinets, or accidents caused by temperature factors. 5Widely used in communications, wind power generation, firefighting equipment, ships, petrochemicals, large factories, coastal factories, docks, water treatment facilities, equipment, etc.
