Thu, 10/14/2010 - 12:21pm

The new Thomas & Betts (T&B — Memphis, TN) Hi-Tech 38kV Trans-Guard OS Short Backup Current-Limiting Fuse provides the greatest risk reduction of disruptive transformer failure. The system is designed for use in 26.4 to 34.5kV distribution while significantly reducing fault energy and offering high interrupting capability for protection against ever-increasing available fault currents. Additional features include:

  • The ability to clear all other currents, such as those resulting from low-impedance faults within the transformer.
  • The capability of interrupting fault currents as high as 50,000 amperes symmetrical.
  • Current-limiting protection for transformers as large as 2,850KVA at 26.4kV; 3,000KVA and 27.6kV; and 3,800KVA at 34.5kV.
