UL/CSA FUSE HOLDERS
The innovative and comprehensive UltraSafe™ range of Mersen
fuse-holders.
Modular fuse-holders are finger-safe under IEC standards to an IP20
grade of protection, including fuse changing (with the flick of a
finger). Modular fuse-holders are available in 1, 2, 3 or 4 poles, with or
without visual blown fuse indicator, in UL + IEC version.
Multi-pole units can also be field assembled by ordering pin-ties
assembly kit. In this size, the range also oers the possibility to use
microswitches (supplied with the holders or ordered separately) to
allow remote indication.
UltraSafe™ range is made of tough and durable thermoplastic or
thermoset material.
