Ferraz Shawmut surge suppression fuses are specially
designed to address the protection of TVSS systems. Surge
suppression fuses have been specially designed to withstand
8x20 mSec surge pulses without opening, allowing the TVSS
system to react to the surge. All surge suppression fuses have
a 8x20 mSec surge rating, not a continuous current rating.
Under AC short circuit conditions these surge suppression
fuses are very current limiting.
Approvals Aplications:
• Protection of TVSS Devices
• Coordination with other
protection devices
