Description:
BK05-BB5D bimetal thermal protector uses high sensitive disk-shaped
bimetal strip as the temperature-sensing element. It is composed of
bimetal strip, moveable contact, stationary contact piece, fixed
base, moveable spring piece, case and temperature resistance lead
wire.The bimetal strip is fixed on the base, which can maintain the
consistency of disconnection and reset temperature after long-term
use. Its' main function is overheating, overload protection.
Working principle: when the temperature rises to a certain value,
the bimetal strip will instantly jump off and the contact will move
quickly to disconnect the circuit. When the temperature falls to a
certain value, the bimetal strip will be reset and the contact will
return to the original state to achieve the purpose of switching
the circuit. Its light weight, compact design maintains the
lightweight, sealed housing of the whole device, and is resistant
to drying, maintaining the accuracy and high reliability of
disconnection and reset throughout its life.
BK05-BB5D 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.
