FLSR080-ID - 80Amp Fuse

FLSR080-ID - 80Amp Fuse

Some electrical loads simply pull more current when they start. Motors and transformers are common examples, and that brief surge doesn't necessarily mean something is wrong. One particularly useful feature in the field is the built-in indication. If the fuse opens, maintenance personnel have a visual clue to help locate the affected fuse—a welcome convenience when you're troubleshooting equipment with several fuses in the same panel.

Key Features and Benefits

• 80A continuous rating for circuits designed around 80-amp fuse protection.
• Class RK5 dual-element construction provides the time-delay response needed for loads with normal startup current.
• Rated up to 600VAC and 300VDC.
• Slo-Blo / time-delay operation allows appropriate short-term inrush current while still responding to sustained overcurrent conditions.
• The built-in indication makes an open fuse easier to spot during inspection and troubleshooting.
• Knife-blade construction fits the appropriate fuse block, clip, or holder.
• Works with the LFR60100 Series PG holder where specified.

Material Compliance and Certifications

The FLSR080-ID is a Class RK5 fuse, an important detail when you're matching a replacement fuse or specifying protection for a piece of equipment. Amperage is only part of the picture. Voltage, fuse class, interrupting capacity, opening characteristics, and physical style also need to meet the application's requirements.

For installations that require specific UL, CSA, RoHS, REACH, environmental, or material-compliance documentation, check the current documentation for the exact FLSR080ID catalog number. That keeps the selection based on the requirements and documentation for the specific part rather than on assumptions from the broader fuse family.

Where It Works Best

The FLSR080-ID is a natural fit for properly specified equipment where brief inrush current is expected. Consider a motor coming up to speed. The current it draws for those first moments can be quite different from what it uses during normal operation. Transformers can behave similarly when they're first energized. A time-delay fuse is useful in these situations because an appropriate, short-lived surge doesn't have to be treated the same way as a sustained overload.

Applications can include motor circuits, transformers, motor-control equipment, industrial machinery, feeders, switchboards, service equipment, and industrial power-distribution systems when their electrical requirements call for Class RK5 protection.
