FRS-R-1 - 1Amp Fuse Description
FRS-R-1 - 1Amp Fuse
The FRS-R-1 is a 1-amp, Class RK5 dual-element fuse designed for electrical equipment requiring a specific combination of a 600 VAC or 300 VDC rating and ferrule-style connections. Physically, this fuse measures 5 inches long and 0.81 inches in height and width, making these dimensions easy to check against existing fuse or equipment specifications. The connection is ferrule end to ferrule end, and the fuse is non-indicating. If your equipment calls for FRS-R-1, you'll want to confirm the full set of specifications—not just the 1A rating—to ensure the fuse class, voltage, interrupting rating, connection, and dimensions match.
