Mersen Fuse Insert NH aR NH3UD69V630PV: additional details
Mersen Protistor fuse inserts 690/700V for semiconductor protection consider a wide range of flexibility in application for protecting modern converter devices. This is a super-fast series that is fully capable of protecting power semiconductors such as diodes, thyristors, GTOs, and IGBT components. The fuse inserts in NH design comply with the regulations according to DIN 43620 and are therefore globally recognized for use in NH fuse bases, NH fuse rails, and NH fuse load disconnect switches. Fuse inserts in various sizes and numerous rated currents allow for extensive device adaptation. The fuses contain melt conductors made of pure silver, embedded in sand, to ensure very good overall breaking integrals (I2t) and high breaking capacities. The contact surfaces are silver-plated and all components are non-magnetic. All fuses in this series feature a functional indicator that, in addition to its visual display function, can also be used to remotely signal the fuse function via an additional microswitch.
