Mersen UltraSafe modular class J fuseholders introduce a
new level of safety and ease for installing or replacing class J fuses.
UltraSafe fuseholders qualify as finger-safe to an IP20 grade of protection
under IEC standards. The US3J accommodates 30A class J or IEC cylindrical
22x58mm fuses. The US6J accommodates 60A class J. UltraSafe fuseholders are
available in compact 1, 2, or 3-pole units, with or without visual blown fuse
indication. Multiple poles can be assembled in the field by ordering and
installing pin-tie handles. US3J and US6J fuseholders can be mounted on 35mm
DIN-rail. Body material is a tough and durable polyamide.
