FLNR040-ID - 40Amp Fuse

FLNR040-ID - 40Amp Fuse

When you need a 40 amp Class R fuse with time-delay protection and easy fault identification, the FLNR040-ID is built for the job. This cartridge-style fuse is rated for 40 amps at 250 VAC and provides a 200 kA interrupting rating, giving compatible electrical systems effective protection against potentially damaging overcurrent conditions. Because it uses a time-delay design, the FLNR040-ID can handle brief, normal current surges without immediately opening, while still responding when an overload or fault persists. It’s also a current-limiting fuse, helping to reduce the fault current that can pass through the circuit under applicable conditions.

Key Features and Benefits

• 40-amp, 250-VAC rating for compatible electrical applications.
• Time-delay operation helps accommodate temporary inrush currents that can occur during normal equipment operation.
• Current-limiting Class R design helps limit fault current under applicable conditions.
• The indicating feature makes it easier to identify an operated fuse during maintenance and troubleshooting.
• Cartridge-style construction is well-suited to applications designed for this fuse configuration.
• Compact dimensions make it easier to match the FLNR040-ID to an existing installation.

Material Compliance and Certifications

The FLNR040-ID is identified in the supplied specifications as a Class R, current-limiting fuse. Specific certification listings, agency approvals, and material or environmental compliance information were not provided in the available product data. If your installation has specific certification or compliance requirements, confirm them using documentation for the exact FLNR040-ID part number.

Where It Works Best

The FLNR040-ID is a good fit for commercial and industrial electrical applications that use a 40-amp, 250 VAC Class R time-delay fuse. Its time-delay characteristic is especially useful in compatible equipment where a brief current surge can be part of normal operation. The indicating feature is handy, too—it can save time when maintenance personnel are tracking down an open fuse.
