FFPowerFuse-gFault Fiter Electronic Power Fuses

Fault Fiter Electronic Power Fuses are a major advancement in circuit-interruption technology. They integrate state-of-the-art electronics with an advanced-design high-continuous-current fFault Fiter® Electronic Power Fuseuse. The electronics provide current sensing, time-current characteristics, and control power. No remote relaying or external power is required. Fault Fiter provides unsurpassed high-speed interruption of fault currents to 40,000 amperes RMS symmetrical. Fault Fiters are maintenance-free, maintenance-proof.

S&C’s Fault Fiter Electronic Power Fuses are manufactured in accordance with a quality system certified to ISO9001:2000.

 

 

Features

Fault Fiter Electronic Power Fuses offer superior coordination with source-side overcurrent relays and load-side feeder fuses. They offer unmatched high-speed circuit-interrupting performance without producing excessive voltage surges, and they respond more quickly to high-current faults than conventional fuses. They’re ideal for:

  • Service-entrance protection and coordination,
  • Transformer protection,
  • Underground subloop protection, and
  • Overdutied device protection.

Fault Fiter Electronic Power Fuses are available with Uni-Rupter®, which provides 400-ampere single-pole live switching of single-phase and three-phase circuits rated 13.8 kV, and 200-ampere single-pole live switching of circuits rated 25 kV. Uni-Rupter offers the ultimate in live-switching simplicity: a firm, steady opening pull on the fuse with a hookstick is all that is required for circuit interruption. Since circuit interruption is internal to Uni-Rupter, there’s no external arc or flame.

Fault Fiter Electronic Power Fuses are offered in S&C Custom Metal-Enclosed Switchgear, S&C PME Pad-Mounted Gear, S&C PMH Pad-Mounted Gear, and wall-mounted S&C Metal-Enclosed Fuses.
