NH Fuse Links Littelfuse European style NH fuse links are designed for the protection of conductors 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.
