FLSR025-ID - 25Amp Fuse

FLSR025-ID - 25Amp Fuse

When you need dependable circuit protection without nuisance trips from normal startup current, the FLSR025-ID is built for the job. This 25-amp Class RK5 time-delay fuse uses dual-element construction and is rated for applications up to 600 VAC or 300 VDC. Its time-delay operation allows the fuse to handle brief, expected current surges—such as those associated with motor starting—while still protecting against sustained overloads and short circuits.

Key Features and Benefits

• 25-amp rating for compatible circuits requiring 25-amp overcurrent protection.
• 600 VAC / 300 VDC maximum voltage ratings cover a wide range of compatible industrial applications.
• Class RK5 construction is suitable for applications designed around this fuse class.
• Time-delay operation allows normal, short-duration inrush currents to pass without unnecessarily opening the circuit.
• Dual-element design combines overload and short-circuit protection characteristics.
• The indicating feature makes it easier to identify an open fuse during troubleshooting.
• Industrial cartridge format installs in compatible fuse blocks, clips, and holders.

Material Compliance and Certifications

The supplied manufacturer information identifies the FLSR025-ID as a Class RK5 fuse. Specific RoHS, REACH, material compliance, or additional certification details were not included in the provided product information, so those claims should not be assumed.

Where It Works Best

This fuse makes the most sense in industrial and commercial electrical systems where short periods of higher current are normal. Motors are a good example. Starting a motor can temporarily draw considerably more current than normal operation, and a time-delay fuse is designed to accommodate an appropriate short-duration surge rather than opening unnecessarily.

The same principle can make the FLSR025-ID useful in compatible transformer circuits, industrial machinery, control equipment, feeders, and electrical distribution applications. Its indicating feature is especially convenient in panels or equipment containing several fuses. Instead of spending extra time determining which fuse has opened, maintenance personnel have a visual indication to help narrow down the problem.
