FLSR060 - 60Amp Fuse

FLSR060 - 60Amp Fuse

When your circuit must handle the normal surge that accompanies starting a motor or energizing a transformer, a fast-opening fuse isn't always the right choice. The FLSR060 is a 60A Class RK5 time-delay fuse designed for exactly that kind of application. Its dual-element construction allows the fuse to ride through appropriate short-term inrush current while still providing protection when an overload lasts too long, or a short circuit occurs.

Key Features and Benefits

• 60A continuous rating for equipment and circuits specified for 60-amp fuse protection.
• Class RK5 construction provides current-limiting overcurrent protection in compatible electrical systems.
• Dual-element design provides time-delay performance while protecting against sustained overloads and short circuits.
• Slo-Blo/time-delay operation helps accommodate normal, temporary startup current without unnecessarily opening.
• Handles applications rated up to 600 VAC or 300 VDC.
• Industrial cartridge format installs in the appropriate fuse block, clip, or holder.
• Non-indicating design for applications where built-in visual fuse indication isn't required.

Material Compliance and Certifications

The FLSR060 is identified as a Class RK5 fuse. If a project requires specific agency approvals, environmental declarations, or material-compliance documentation, check the current documentation for the exact FLSR060 catalog number before specifying it. This is particularly important when a facility needs records for requirements such as UL, CSA, RoHS, REACH, or other applicable standards rather than simply confirming the fuse's electrical ratings.

Where It Works Best

The FLSR060 makes sense in circuits where brief current surges are normal, but a sustained overload still needs dependable protection. Motors and transformers are two good examples. Both can draw considerably more current when first energized than when operating normally. The fuse's time-delay characteristic allows it to tolerate appropriate short-duration inrush rather than treating every startup surge as a fault.

You'll commonly find this type of 60A Class RK5 time-delay fuse suited to properly specified motor circuits, transformers, industrial machinery, motor-control equipment, switchboards, feeders, service equipment, and general power-distribution circuits. Its 600VAC rating also gives designers and maintenance personnel flexibility in equipment that requires a fuse with a higher AC voltage rating.
