SM/G SERIES

q

If caulking or welding, be careful to keep the resistance value of the connecting section low.

If the connecting section has a high resistance value, the passing current may generate an abnormally high

temperature that will cause the thermal cutoff to operate (break the circuit).

q

It is recommended that the connecting position at the lead of resign-sealed side should be 5 mm or more from

the body of the thermal cutoff.

Position of installation

q

After mounting the thermal cutoff, be careful not to apply force that may pull, push or twist the lead wires.

Recommendation

q

Be careful when mounting the thermal cutoff because external force, heat, or a harmful atmosphere (contain-

ing excessive humidity or sulfurous acid gas) may damage the characteristics of the thermal cutoff. If appli-

cable, it is recommended to warn general consumers who are not aware of the usage cautions for the thermal

cutoff not to mount, remove or replace the thermal cutoff through a note to this effect in the user's manual and

other related material.

If you desire any clarifications or explanations regarding these cautions, please call an NEC sales

representative.
