FRS-R-150 - 150Amp Fuse

FRS-R-150 - 150Amp Fuse

When you're replacing a fuse, the 150 amp rating is only one part of the match. It uses blade connections at both ends and measures 9.63 inches long, so checking the physical fit is just as important as confirming the electrical ratings. The fuse is also non-indicating, meaning it doesn't provide a built-in visual indication of fuse status. If you're replacing an existing FRS-R-150, compare the catalog number and the full set of ratings with the equipment documentation before installation. That quick check can prevent a simple part-number search from turning into a specification mismatch.

Key Features and Benefits

• 150 amp, Class RK5 design: Matches equipment specifically calling for this amperage and fuse class.
• 600 VAC / 300 VDC rated: Provides clearly defined AC and DC voltage ratings for easier specification matching.
• Dual-element construction: Provides the dual-element configuration specified for the FRS-R-150.
• Defined response characteristic: Manufacturer specification is 10 seconds at 500% of rated current.
• Blade end-to-blade end connection: Provides technicians with another important physical detail to verify against the existing equipment.
• Non-indicating: No built-in visual fuse-status indicator.
• CE Marked: Compliance status is identified in the supplied manufacturer specifications.

Material Compliance and Certifications

The FRS-R-150 is CE-marked according to the supplied manufacturer information. No other material-compliance declarations or certifications were included in the specifications provided, so none are claimed here.

Where It Works Best

The FRS-R-150 makes sense where the equipment specifically calls for a 150A Class RK5 dual-element fuse with compatible 600 VAC or 300 VDC ratings and a blade-end connection. Because the fuse is 9.63 inches long and 1.84 inches in both height and width, physical fit should also be confirmed before installation.
