TM USCC & USM ULTRASAFE FUSEHOLDERS ULTRASAFE MODULAR FUSE HOLDERS Ferraz Shawmut UltraSafe™Modular Fuse Holders introduce a new level of safety for Class CC (USCC) and Midget 1-1/2” x 13/32” (USM) 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. Multi-pole 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 holders with Class CC fuses chosen for Type “2” No Damage protection give one of the safest protection packages in the industry. UltraSafe body material is tough and durable polyamide, with exceptional insulating properties.
