Ultrasafe Fuseholders - USM Series
Ferraz Shawmut ULTRASAFE modular 24, 48 and 600 volt Fuse Holders introduce a new level of safety for Midget 1-1/2" x 13/32" as well as 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 blown-fuse indicators in each pole. AC indicators are orange and DC are red. The multi-pole units can also be made up by ordering pin-tie handles for field assembly. 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.
