FLSR17.5 - 17½ Amp Fuse

FLSR17.5 - 17½ Amp Fuse

When your equipment calls for a 17.5A Class RK5 time-delay fuse, getting the details right matters. The FLSR17.5 combines a 17.5-amp continuous current rating, 600V AC maximum voltage, and 300V DC maximum voltage in an industrial cartridge-style fuse.

Key Features and Benefits

• 17.5A continuous current rating – A fractional-amperage option for equipment specifically requiring a 17.5-amp fuse.
• Class RK5 configuration – Helps make replacement matching more precise when the equipment specifies an RK5 fuse.
• 600 V AC maximum rating – Suitable for properly specified AC applications up to 600 V.
• 300 V DC maximum rating – Also rated for compatible DC circuits up to 300 V.
• Slo-Blo / time-delay operation – Gives brief, acceptable inrush currents time to pass rather than reacting like a fast-acting fuse.
• Dual-element construction – Provides the time-delay operating characteristics associated with the FLSR series.
• Industrial cartridge design – Made for installation in a compatible fuse block, clip, or holder.
• Non-indicating fuse – The FLSR17.5 does not include a fuse-status indication feature.

Material Compliance and Certifications

The available manufacturer information identifies the FLSR17.5 as a Class RK5 fuse. However, the supplied specifications do not provide sufficient information to accurately state the individual UL, CSA, RoHS, or other material compliance certifications for this exact catalog number.

Where It Works Best

The FLSR17.5 is a practical choice when the equipment specifically requires a 17.5A Class RK5 time-delay fuse and brief inrush or startup current is expected during normal operation. The time-delay characteristic is the important part here: it gives short-lived current increases some breathing room while retaining the fuse's intended overcurrent-protection function.
