Specifications: Material: Metal, plastics, ceramics Voltage: AC 250V Current: 16A Temperature Range: 50°C - 300°C / 50°C - 400°C Product Life: > 100,000 cycles Electric Strength: AC 2000V / 1 min Normal Insulation Resistance: 100MΩ Contact Resistance: 50mΩ Wet Insulation Resistance: 10MΩ Temperature Response Rate: 1.0°C / min Minimum Current: 200mA Rod Diameter: 5mm / 6mm Rod Length: 54mm / 35mm Cable Length: 70cm Principle of Performance: When the temperature of the controlled object changes, the working fluid inside the thermostat reacts accordingly. This causes thermal expansion or contraction (change in working fluid volume), which acts on the temperature-sensing bellows. The movement of the bellows is transmitted through a lever mechanism to operate the switch, achieving automatic temperature control. Suitable for: Household appliances (showers, drum washing machines, heaters), Electrical equipment (stainless steel automatic water boilers, electric frying pans, food machinery, medical equipment), Refrigeration industry (kitchen freezers, fresh cabinets, refrigerators, ice machines, fish ponds, cold drink machines, heating units) requiring temperature control. Package Includes: 1 x Mechanical Thermostat Set
