FLSR200 - 200Amp Fuse

FLSR200 - 200Amp Fuse

When you're replacing a 200A Class RK5 fuse, the amperage printed on the label is only part of the story. The FLSR200 brings together a 200-amp continuous current rating, 600V AC maximum voltage, 300V DC maximum voltage, and dual-element time-delay operation in a knife-blade configuration.

Key Features and Benefits

• 200A continuous current rating – Matches equipment and circuits specifically requiring a 200-amp fuse.
• Class RK5 fuse – An important classification to verify when replacing an existing fuse.
• 600V AC maximum rating – Suitable for compatible AC systems operating within the fuse's published specifications.
• 300V DC maximum rating – Can also be used in properly specified DC applications up to 300V DC.
• Slo-Blo / time-delay operation – Accommodates appropriate temporary inrush or startup current without opening unnecessarily.
• Dual-element construction – Delivers the time-delay operating characteristics specified for the FLSR200.
• Knife-blade configuration – Made for installation in a compatible fuse block, clip, or holder.

Material Compliance and Certifications

The available product information identifies the FLSR200 as a Class RK5 fuse. However, the supplied specifications do not include sufficient catalog-specific information to accurately state individual UL, CSA, RoHS, or other material compliance certifications.

Where It Works Best

The FLSR200 is a strong fit for electrical equipment that specifically requires a 200A Class RK5 time-delay fuse and may experience acceptable short-duration inrush or startup current during normal operation. The time-delay characteristic is the key distinction here—it allows brief current increases to occur while maintaining the fuse's intended overcurrent-protection function.

For replacement work, don't choose a fuse based on 200 amps alone. Check the complete equipment requirements. The correct replacement should match the required Class RK5 designation, 200A current rating, voltage rating, time-delay characteristic, interrupting capacity, non-indicating configuration, and knife-blade construction.
