NH Fuse Links
Littelfuse European style NH fuse links are designed for the protection of conduc-
tors and motors. The gL-gG characteristic fuse links are generally used to protect
cables and installation lines from overload and short circuits. The aM characteristic
fuse links are used for the short circuit protection of motors and switchgear. They
are available in NH00C to NH3 sizes up to 630 amperes.
