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: 100 MΩ Contact Resistance: 50 mΩ Humidity Insulation Resistance: 10 MΩ Temperature Response Rate: 1.0°C / min Minimum Current: 200 mA Rod Diameter: 5 mm or 6 mm Rod Length: 54 mm or 35 mm Cable Length: 70 cm Principle of Performance: When the temperature of the controlled object changes, the working fluid inside the thermostat expands or contracts accordingly due to thermal expansion and contraction. This physical change in volume acts on a temperature-sensing bellows, which expands or contracts. Through a mechanical lever mechanism, this movement drives the switch to open or close, achieving constant temperature control. Suitable for: Household appliances (showers, drum-type 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 machines) requiring temperature control Package Includes: 1 set of mechanical thermostat
