1. KSD9700 series Cut Off Switch’s Principle and structure
KSD9700 serial universal and enhanced protectors with large metal
casing are composed of the thermal conductive metal casing,
bimetallic parts welded with silver alloy contact point, conductive
bracket, insulation fixation stand, fixed contact strip and heat
resistance cable. In case of abnormal operation, along with the
increase of the environment temperature to the set value, the
bimetallic parts perform quick action, open the contact point, and
disconnect the circuit. When the device is cooled to the
temperature for safe operation, the contact point will
automatically closes and recover normal operation.
KSD9700 thermal cutoff switch 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.
Product features: KSD9700 theraml overload prtoector is a
temperature control switch developed by imported thermal bimetal,
with small size, rapid action, accurate temperature control and
long life cycle.
