UL/CSA Fuse Holders

USM - Midget
Mersen UltraSafe modular fuseholders introduce a new level of safety for class CC and midget fuses up to 30 amperes. UltraSafe fuseholders 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 fuseholders are available in 1, 2, 3 or 4 poles, with or without visual blown-fuse indicators in each pole. Multiple poles can be assembled in the field by ordering and installing pin-tie handles. UltraSafe fuseholders save up to 15% mounting space and any combination can be snapped onto 35mm DIN rail for extra savings in panel building time. Choose class CC fuses for Type "2" no-damage protection, one of the safest protection packages in the industry. The UltraSafe body material is tough and durable polyamide, with exceptional insulating properties.
