Bimetal thermostats are also known as snap action thermostats. Our leading products are 3/4-inch and 1/2-inch thermostats. The 3/4-inch thermostats can be used as substitutes for Emerson (T.O.D) 60T. The maximum current carried by the thermostat can be up to 60 A. It can be applied to electrical equipment with a rated power of 10 KW. The 1/2-inch thermostats can be used as substitutes for Emerson (T.O.D) 36T. This thermostat features a small size, high sensitivity, accurate temperature control, and a rated current of up to 16 A. It can be applied to household electrical equipment with a rated power of 3 KW. The operating principle of the two thermostats is as follows: When the temperature of the heating element rises to the temperature set by the bimetal thermostats, the push rod is pushed through the bending deformation of the bimetal to break the circuit from the surface. Several models of these thermostats come with dual temperature protection. When the temperature control part fails and the circuit cannot be cut off at a certain temperature, backup protection will be started to cut off the circuit when the temperature continues to rise to the temperature set by another set of temperature limits. The temperature can be set according to customers’ needs.
