The 690/700V Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for small power conversion equipment. These ultra-fast acting aR fuses have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors and IGBT devices.

They 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.

Features :

• aR Class according to IEC 60269-4 and VDE 636-23

• Very low I²t for improved semicon-ductor protection

• Ultra fast acting

• Superior cycling capability

Application

Protection of inverters, motor drives, UPS systems and similar 690V or less equipments.
