Description:
BK05-BB1D Series Thermal Protector is a kind of
temperature-sensitive bimetallic disc used as a heat-sensitive
reaction component. When the temperature of the main product of the
product is increased, the heat generated is transferred to the
bimetallic disc. When the operating temperature is set, it will act
quickly and act through the mechanism. The contact is opened or
closed; when the temperature drops to the reset temperature
setting, the bimetallic disc quickly returns to its original state,
and the contact is closed or opened to achieve the purpose of
connecting or disconnecting the circuit, thereby controlling the
circuit.
BK05 series thermal protector is small in size, sensitive to
temperature, accurate and reliable protection, especially suitable
for the safety protection of temperature sensing cable, battery
protection board, micro motor and transformer, etc.
