Features: Normally closed thermal switch means that the contacts of thermal switch normally remain closed. When temperature increases to the set value, the contacts would open and cut the circuit OFF. The switch is working under AC250V 16A of power supply. Ceramic insulator material design can provide better protection. Compact and practical design makes it works more stable. Application: Suitable for Household electric appliances, PC, Microwave ovens, Irons, Refrigerators, Electronic oven, heating unit, coffeepot, water heaters, etc. Notice: 1.Actual color may be slightly different from the image due to different light effect 2.Please allow 1-3cm deviation due to manual measurement Description: Body material: ceramic Switch type: normally closed Working voltage:110V,250V,400VV Overload current:10A,15A,20A,40A,60A Operating temperature:0 degree to 300 degrees °C Contact resistance: 50mohm Insulation resistance: 100Mohm, Contact form: normally closed type: the temperature rises, the contact is disconnected, the temperature falls, the contact is connected; Normally open type: temperature rises, contact is on, temperature falls, contact is off. Shell protection grade: IP00 Grounding method: through the thermostat metal shell and device grounding metal parts connected. Installation: directly reinforced with dowel can be.
