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 fuse. 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.
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
