FLNR200 - 200 Amp Fuse

FLNR200 - 200 Amp Fuse

The FLNR200 is a 200-amp Class RK5 time-delay fuse designed for your electrical applications where temporary current surges are expected, yet dependable overcurrent protection remains essential. Its dual-element, Slo-Blo design allows the fuse to handle brief inrush currents—such as those encountered when motors start or equipment is energized—without opening unnecessarily. Rated for 250VAC and 125VDC, the FLNR200 uses a traditional knife-blade configuration and installs in a compatible fuse block, clip, or holder. It also offers substantial fault-current interruption capability, with ratings up to 300 kA AC and 20 kA DC.

Key Features and Benefits

• 200-amp continuous rating for applications requiring a 200A fuse.

Material Compliance and Certifications

The FLNR200 is classified as a Class RK5 fuse. The product information provided for this listing does not specify individual material compliance declarations, such as RoHS, REACH, or lead-free status. If your installation or project requires a particular material declaration or certification, confirm the applicable documentation for the exact FLNR200 catalog number before installation.

Where It Works Best

The FLNR200 makes sense in commercial and industrial electrical systems where equipment can draw a short burst of additional current during startup. Motors, transformers, machinery, and similar electrical loads are common examples of equipment where time-delay characteristics can be useful. Instead of reacting immediately to an expected, short-duration inrush, the fuse is designed to provide the time-delay behavior specified for this type of application while still protecting against sustained overcurrent conditions.

It can also be a good fit when servicing existing equipment that specifically calls for a 200A, 250VAC Class RK5 time-delay fuse with knife-blade construction. That's an important distinction because amperage is only one part of choosing a replacement fuse.
