RF/RFS
Class H
Traditional protection for circuits with less than 10,000A
RF and RFS general purpose fuses are suitable for applications where available short
circuit currents do not exceed 10,000 amperes. RF and RFS renewable fuses use
matched RL and RLS die-cut zinc links from 1 to 600 amperes in
32 ratings.
Features/Benefits:
•
Knurled bushings for ease of disassembly
•
Rugged construction for maximum service life
•
Precision die-cut renewal links renew quickly and give repeatable
performance
Highlights:
Applications:
or less
•
Renewable
•
32 Renewable link ratings
•
General purpose loads where
short circuits are 10,000 amperes
