Fuses

These Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for today's power conversion equipment. These 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, GTO's and IGBT devices. Fuses are assembled with pure silver, 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.
All fuse-links can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.

Mersen NRN (250V) and NRS (600V) fuses are standard non-time delay fuses, with a 10kA short circuit rating. 250 Volt NRN 15 amp through 60 amp fuses are certified as Type "P" fuses, satisfying the Canadian Electrical Code for low melting-point non-time delay fuses. Also qualifying for Type "P" are OTN15 through OTN60, which are Class K-5 fuses with a 50kA short circuit rating (found in the OT/OTS section of this cata log).
