FLSR003-ID - 3Amp Fuse

FLSR003-ID - 3Amp Fuse

When your circuit experiences a brief startup surge, you don’t necessarily want the fuse to open when nothing is actually wrong. The FLSR003-ID 3A Class RK5 fuse features a dual-element, time-delay design that handles normal temporary inrush currents while providing overcurrent protection for properly rated electrical equipment. Rated for 3 amps, 600VAC, and 300VDC, this industrial cartridge fuse also includes an indicating feature that makes an open fuse easier to spot during troubleshooting. That small detail can make a real difference when maintenance teams are trying to locate a fault and get equipment back in service.

Key Features and Benefits

• 3-amp continuous current rating for appropriately specified electrical circuits.
• 600 VAC and 300 VDC maximum voltage ratings provide flexibility for compatible AC and DC equipment.
• Class RK5, dual-element construction combines time-delay operation with overcurrent protection.
• The time-delay opening characteristic helps accommodate temporary startup and inrush currents that can occur with inductive loads.
• The built-in indication makes an open fuse easier to identify during inspection and troubleshooting.
• Industrial cartridge design fits compatible fuse blocks, clips, and holders.
• Designed for compatibility with the LFR60030 Series holder family.

Material Compliance and Certifications

The FLSR003-ID belongs to an established industrial fuse family intended for properly specified electrical protection applications. Because material compliance and certification requirements can vary by application and project, any required UL, CSA, RoHS, REACH, or other compliance documentation should be confirmed for the specific FLSR003-ID catalog number before installation.

Where It Works Best

The FLSR003-ID 3A fuse is a strong match for electrical applications where brief inrush currents are part of normal operation. Motors, transformers, industrial machinery, control circuits, and other compatible inductive loads are common examples.

It also makes sense in environments where maintenance time matters. Because the fuse indicator shows which fuse is open, technicians can more readily locate it instead of spending unnecessary time checking individual components. That makes the FLSR003-ID particularly useful in busy industrial panels and equipment where troubleshooting needs to be straightforward.
