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.
