Maxium temperature limit(TM): The maximum temperature at which a Thermal Cutoff can be maimtained for
10 minutes without reclosing the fuse will not change its state, until reaches rated temperature
Holding temperature (TH): The maximum temperature at which a thermal Cutoff will not cause a change in state
of conductivity to open circuit while conducting rated current Rated fuaction temperature(TF): The temperature at which a Thermal Cutoff changes its state of conductivity to
open circuit detection curret, the tolerance of temperature are +0 -5 degrees

USE NOTE:
When in welding, attention should be paid not to make welding heat too high to cause
fusible heat protector to operate. In order to avoid this from happenn, fixtures can be used
around the cover of safety pipe so that heat will be distributed and work can be done in
short period. Also reducing welding temperature or be away from safe pipe body is also
helpful
When in riveting or heat sealing, attention should be paid not to increase resistance
If the resistance from connector is too large, it will cause abnormal heat and cause
fusible heat protector to operate when going through current.
Especially in riveting, resistance will be increased due to influence from heat cycle or
temperature. Please make careful consideration for this.
After fusible heat protector is installed, please do not pull, turn or twist down leads.
When using RYD fusible protector, please do not let resin side down-lead have contact
with the body from fusible heat protector. If resin side down-lead has contacts with the
body, then the electric current will go to the other end of lead through the body, so circuit
cannot be cut
When electric current goes through the body of RYD fusible heat protector, please do
not let the body from fusible heat protector have contact with metal parts from installation
position
