FLSR070-ID - 70Amp Fuse

FLSR070-ID - 70Amp Fuse

The FLSR070-ID is designed for your electrical systems that require 70A Class RK5 protection without treating every brief startup surge as a fault. Motors, transformers, and similar equipment can pull extra current when they're first energized. That's where the time-delay design comes in. The FLSR070-ID can handle appropriate short-duration inrush while still protecting against sustained overloads and short circuits.

Key Features and Benefits

• 70A continuous rating for circuits requiring 70-amp fuse protection.
• Class RK5 dual-element design provides time-delay operation along with overload and short-circuit protection.
• Handles applications rated up to 600 VAC or 300 VDC.
• The Slo-Blo / time-delay characteristic helps the fuse tolerate appropriate temporary startup and inrush current.
• Indicating design makes an open fuse easier to spot during maintenance and troubleshooting.
• Knife-blade construction is well-suited to applications designed for this style of industrial fuse.
• Designed for installation using the appropriate fuse block, clip, or holder.
• Specified for use with the LFR60100 Series PG holder.

Material Compliance and Certifications

The FLSR070-ID is a Class RK5 fuse, but fuse class and amperage aren't the only details that matter when you're matching a fuse to a piece of equipment. The voltage rating, interrupting capacity, time-delay requirement, physical style, and equipment specifications need to line up as well.

If your application requires specific agency approvals or environmental and material compliance documentation, check the current documentation for the exact FLSR070ID catalog number. Requirements such as UL, CSA, RoHS, or REACH should be confirmed for this specific part rather than assumed based on other products in the same family.

Where It Works Best

This fuse is especially useful in circuits where a brief current surge is normal. A motor, for example, can draw considerably more current when it starts than when it's running. A transformer can also experience an initial inrush when energized. The FLSR070-ID's time-delay characteristic is intended to accommodate appropriate short-lived conditions like these while still responding when an overcurrent condition persists.

That makes the FLSR070-ID a potential fit for properly specified motor circuits, transformers, industrial machinery, motor-control equipment, feeders, switchboards, service equipment, and power-distribution systems requiring a 70A Class RK5 time-delay fuse.
