DCT
Special Purpose Midget Fuses
Mersen DCT fuses were developed to meet requirements coming from new
applications such as protection of photovoltaic cells, multi meters and compact on
board traction equipment for auxiliary circuits. This high performance DC fuse in its
compact size offers multiple competitive advantages particularly for international
applications where DC voltage requirements are above 600V DC.
