FUSE HOLDERS, FUSE BASES AND SUPPORTS

IEC+UL/CSA FUSE HOLDERS

Mersen’s innovative Modulostar CUS10 fuse holders are finger-safe

under IEC standards to an IP20 grade of protection, including fuse

changing (with the flick of a finger). Modulostar CUS10 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. Made of tough and

durable thermoplastic or thermoset material. For use with Mersen

midget fuses.

The 690/700V Protistor® fuse-links provide maximum flexibility

in equipment design and ultimate protection for today’s power

conversion equipment. These aR ultra-fast acting square body

fuse-links are available in different body sizes, each size having

multiple worldwide acceptable mounting styles.

The Protistor® have been engineered to provide state-of-the-art

protection for semiconductors: diodes, thyristors and IGBT devices.

Fuses are assembled with die-cut elements embedded in solidified

sand, which helps control arcing characteristics for a lower I²t and

high interrupting rating level. All contact surfaces are silver plated

and all hardware is non-magnetic.

Each fuse-link can be equipped with a low voltage trip-indicator

which can operate a field mountable microswitch.
