A fuse holder (100) includes a housing (104) and a knob (108). The housing has a telescoping chamber designed to receive a knob terminal (106), where the knob terminal is adapted to receive a fuse. The knob has a neck (110) which is inserted into the telescoping chamber to enclose the cylindrical fuse. The housing and neck are made of a polymer having a thermal conductivity in a range of 4.0 to 10 W/mK.

The subsea fuse assembly comprises an enclosure (11) filled with a dielectric fluid (80) and provided with an equalization opening (22, 32), which is sealed with a flexible element (40). A first electric conductor (61) extends into the enclosure through a first lead-through (70) positioned in a wall (15) of the enclosure. A second electric conductor (62) is attached to an inner surface of a wall (14) of the enclosure. A fuse (50) is connected between the first electric conductor and the second electric conductor within the enclosure. A third electric conductor (63) extends outside the enclosure and is attached to an outer surface of a wall of the enclosure. An electrically conductive path is thus provided between the second electric conductor and the third electric conductor through the electrically conductive enclosure.
