All NH fuse links incorporate a blown fuse indicator.
NH Fuse Links
500 Volts • 2 – 630 Amperes
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 overloads 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.
