UL/CSA FUSE HOLDERS
The innovative and comprehensive Modulostar® range of Mersen
fuse-holders.
Modular fuse-holers are finger-safe inder IEC standards to an IP20
grade of protection. Including fuse changing, with the flick of a finger.
Modular fuse-holders in size 27 are available in 1, 2 or 3 poles, with or
without visual blown fuse indicators, in IEC + UL version.
Multi-pole units can also be field assembled by ordering pin-ties
assembly kit. In size 27 the range oers the possibility to use
microswitches (supplied with the holders or ordered seperatly) to
allow remote indication. Modulostar® range is made of tough and
durable thermoplastic or thermoset material.
