38-kV Fault Tamer^® Fuse Limiter Now Available

S&C is pleased to introduce the new 38-kV Fault Tamer Fuse Limiter, which is available now.  This new model was developed in response to requests for a two-component fusing system for use at 38 kV, having the energy-limitation and power-quality advantages of conventional current-limiting fuses — but with the additional features and benefits inherent to Fault Tamer.  Such benefits include retrofittability, ease of installation and removal, and no expelled parts. The new 38-kV Fault Tamer fits these requirements perfectly.

The backup limiter has the same size and shape as the 25-kV backup limiter, but contains an additional length of ribbon element as required to successfully clear faults on 38-kV systems. The molded cover prominently identifies the 38-kV maximum voltage rating of the 38-kV backup limiter, to help ensure the device is properly applied.

The new 38-kV series fuse tube design represents a departure from the fuse tubes used on 15-kV and 25-kV Fault Tamers. Instead of an engineered plastic molding, the new fuse tube utilizes the same MultiWind™ material as in Type XS Fuse Cutout fuse tubes. This material is stronger and has equivalent or better arc-interrupting properties.

The continuous-current rating of the 38-kV Fault Tamer is 20 amperes, the same as the rating for both 15-kV and 25-kV models. The 38-kV Fault Tamer can protect a wide range of overhead distribution transformers rated through 250 kVA single phase and 750 kVA three phase.

38-kV Fault Tamer Fuse Limiters use the same fuse cartridges as 15-kV and 25-kV Fault Tamers.
