AMP-TRAP?–Form 101
A70P
SEMICONDUCTOR PROTECTION FUSES
A70P Amp-trap?Form 101 Semiconductor Protection
fuses were developed for higher voltage AC and DC
drives, UPS systems, reduced voltage motor starters
and similar applications where lower l2t and superior
reliability were needed. A70P is a very popular fuse,
available in a wide range of ratings. Typically used for
replacement.
