!Caution/Notice
!Caution
(Rating)
1. Do not use products beyond the rated current as
this may create excessive heat and deteriorate
the insulation resistance.
2. Be sure to provide an appropriate fail-safe
function on your product to prevent a second damage
that may be caused by the abnormal function or
the failure our product.
Notice
BLM series should be used within 6 months.
Products to be used after this period should
be checked for bondability with glue.
