FRS-R-17.5 - 17.5 Amp Fuse

FRS-R-17.5 - 17.5 Amp Fuse

When you're matching a replacement fuse, 17.5 amps is only the beginning of the specification check. This model uses ferrule ends on both sides and has a non-indicating design. At 5 inches long and 0.81 inches in both height and width, its dimensions are straightforward to compare with an existing fuse or equipment specifications. For electricians and maintenance teams, that combination of catalog number, amperage, fuse class, voltage ratings, connection style, and physical size provides the details needed for a more complete compatibility check—not simply a visual match.

Key Features and Benefits

• 17.5A Class RK5 rating makes the amperage and fuse class easy to identify when checking equipment requirements.
• Rated for 600 VAC and 300 VDC, providing clearly defined specifications for compatible AC and DC equipment.
• Dual-element design with a stated response time of 10 seconds at 500% of rated current.
• Ferrule end x ferrule end connection gives you another important physical characteristic to verify during replacement.
• Non-indicating design means there is no built-in fuse status indicator.
• Measures 5 inches long by 0.81 inches high by 0.81 inches wide, making physical dimensions easy to check against the existing installation.

Where It Works Best

The FRS-R-17.5 17.5A fuse is best suited for compatible electrical equipment that specifically requires a Class RK5 dual-element fuse with ferrule-end connections and matching electrical ratings. Its combination of a 17.5A rating, 600 VAC / 300 VDC voltage ratings, and published AC and DC interrupting ratings gives maintenance personnel several concrete specifications to check against equipment documentation.
