What is a HCET thermal protector?
How does HCET thermal protector work?
The design principle of the Thermal protector switch is to use bimetallic plates to make switches or relays.
Two layers of alloys with different thermal expansion coefficients are laminated to form bimetallic plates.
The active layer has a large expansion coefficient， whose passive layer is small. When the temperature rises,
the bimetal will bend and deform due to the different expansion coefficients of the active layer and the passive
layer. When the temperature is restored, the shape of the bimetal will also recover, thus forming a switch that
closes and opens according to temperature changes. When installing the thermal protector, it is necessary to
ensure that the thermal protector closer to the source of heat.
Features of HCET thermal protector
The bimetallic thermal switch / thermal protector should be able to follow the thermal overload caused by the
rapid or slow change of the temperature of the protected device, so it can closely match the thermal characteristics
of the protected object and the correct choice can play a role. The thermal protector has the characteristics and
advantages of round shape, smaller size, good sealed, stable and reliable performance, easy installation, and competitive price.
With the company's mature technical strength and sound management system, to provide customers with cost-effective products and services.
