Metal Case Temperature Control BW Thermal Protector 200C 250C Electric Motor Thermal Switch
Principle and Characteristics of Metal Case Temperature Control BW Thermal Protector 200C 250C Electric Motor Thermal Switch
The BW-type thermal protector is made up of a disk-shaped and high
sensitive bimetallic element, a traveling contact, a statics
contact, a ledger plate,a shell,heat-resistant wires etc. When the
protector works,the bimetallic element is free and unlocked , the
traveling contact and the statics contact closes,the main circuit
is in conducting state.If the protector gives out heat for some
reason, the temperature will rise up and as if it gets to the
rating action temperature,the bimetalic element will react rapidly
because of the inner stress for the heat,which can promote the
traveling contact so as to disconnect the contact and cut off the
power supply to have a protective effect. When the temperature
drops to the rating reset temperature,the bimetallic element
returns to the initial state, the traveling contacts close,the
protector recovers to work and loops in this way. The product has
the advantages:very little resistance,temperature-sensing,acted
quicky,Safe and reliable,small, light etc.
Product Advantages of Metal Case Temperature Control BW Thermal Protector 200C 250C Electric Motor Thermal Switch
BW Thermal Protector Up To 250°C
In general, the highest temperature is 160°C for BW thermal protector. But our BW thermal protector can up to 250C. It has the characteristics of small size, rapid action, precise temperature control, large control current and long service life.
