FLSR020-ID - 20Amp Fuse

FLSR020-ID - 20Amp Fuse

When your circuit needs reliable protection while also handling the brief current surge that can occur during startup, the FLSR020-ID is built for the job. This 20A Class RK5 time-delay fuse features dual-element construction and is rated for applications up to 600VAC or 300VDC. Its time-delay operation helps the fuse ride through normal, short-duration inrush current while still protecting against sustained overloads and short circuits. One especially useful feature is the built-in open-fuse indication.

Key Features and Benefits

• 20-amp rating for equipment and circuits requiring a 20A Class RK5 fuse.
• Handles applications rated up to 600 VAC and 300 VDC.
• Time-delay operation helps prevent unnecessary fuse opening during normal temporary current surges.
• Dual-element design combines time-delay performance with overload and short-circuit protection.
• The indicating feature provides a convenient visual reference when the fuse has opened.
• Class RK5 construction is designed for current-limiting overcurrent protection in compatible applications.
• Industrial cartridge format works with the appropriate fuse blocks, clips, and holders.

Material Compliance and Certifications

The FLSR020-ID is identified as a Class RK5 industrial fuse. The product information supplied for this listing does not provide specific details on individual material compliance declarations or certifications, such as RoHS or REACH. If those requirements are important for your facility or project, confirm the applicable documentation for the exact FLSR020ID part number before installation.

Where It Works Best

The FLSR020-ID 20A time-delay fuse makes sense in industrial electrical systems where temporary inrush current is normal. Motors and transformers are good examples: startup or energization can briefly draw considerably more current than normal operation. The time-delay characteristic is designed to accommodate appropriate short-duration surges without sacrificing protection against sustained overloads and short-circuit conditions.
