Key features & benefits

Mersen USM Series UltraSafe Modular Fuse holders introduce a new level of safety for Midget 1-1/2" x 13/32" AC and DC-rated fuses up to 30 amperes. UltraSafe holders qualify as “Finger-safe” under IEC and DIN standards to an IP20 grade of protection, including fuse changing (with the flick of a finger). UltraSafe holders are available in 1, 2, 3 or 4 poles, with or without visual blown-fuse indicators in each pole. Multipole units can also be field assembled by ordering pin-tie handles.
UltraSafe holders save up to 15% mounting space and any combination can be snapped onto 35mm DIN-rail for extra savings in panel building time. UltraSafe body material is tough and durable polyamide, with exceptional insulating properties.
