FLNR020 - 20 Amp Fuse

FLNR020 - 20 Amp Fuse

When your circuit calls for a 20 amp Class R fuse, the FLNR020 provides the combination of protection and practical features needed for demanding electrical applications. This 250 VAC cartridge-style fuse has a 200 kA interrupting rating and uses a current-limiting, time-delay design. That time delay matters for equipment that experiences a brief current surge during startup—it allows normal short-duration inrush current while still providing overcurrent protection when conditions require the fuse to operate. The FLNR020 also includes an indicating feature that can make troubleshooting a little easier by helping maintenance personnel spot an open fuse.

Key Features and Benefits

• 20A, 250 VAC rating for compatible commercial and industrial electrical applications.
• Time-delay design accommodates brief inrush currents that can occur during equipment startup.
• Current-limiting Class R fuse construction helps limit fault current when the fuse operates under appropriate conditions.
• The built-in indication helps maintenance personnel identify an open fuse more quickly.
• Cartridge-style format is well-suited to applications designed for this type of Class R fuse.
• Compact 2.0 x 0.56 x 0.56-inch size makes physical specifications easy to check when matching an existing fuse.

Where It Works Best

The FLNR020 20-amp fuse is a practical choice for compatible commercial and industrial equipment requiring 250 VAC Class R time-delay protection. It can be suited to applications such as properly rated motor circuits, transformers, industrial machinery, control equipment, and electrical distribution equipment where temporary startup current is expected.

Its indicating design is particularly handy in maintenance environments. When you're tracking down an electrical problem, being able to identify an open fuse without unnecessary guesswork can save time.
