Porta's Series 575 Sneak Current Fuse Assemblies detect over-currents and
react by
opening the line. Like home circuit breakers, these devices stop the flow
of current, preventing the heating and burning of wire in risers and
ducts.
Sneak Current Fuse Assemblies should be installed before the PBX or KSU.
Features:
- Dependable sneak current protection for
up to 25 lines
- Same mounting footprint as standard
66-type block
- UL 497A listed - Secondary Protection
- Sturdy, UL94-V0 fire-retardant housing
- Stops current overloads that can cause
fires in walls and floors
- Eliminates costly service calls and
repairs
