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 l
2
t and superior
reliability were needed. A70P is a very popular fuse,
available in a wide range of ratings. Typically used for
replacement.
