FLSR225-ID - 225Amp Fuse

FLSR225-ID - 225Amp Fuse

When you're tracking down the right replacement fuse, the amperage printed on the label is only part of the story. The FLSR225-ID is a 225A Class RK5 indicating time-delay fuse with a 600V AC and 300V DC maximum voltage rating, dual-element construction, and a knife-blade configuration. Its Slo-Blo/time-delay operation allows the fuse to accommodate appropriate short-duration inrush or startup currents rather than respond like a fast-acting fuse.

Key Features and Benefits

• 225A continuous current rating – Matches equipment and circuits specifically requiring a 225-amp Class RK5 fuse.
• Up to 600V AC – Suitable for correctly specified AC applications within its published voltage rating.
• Up to 300V DC – Provides flexibility for compatible DC applications as well.
• Slo-Blo / time-delay operation – Accommodates appropriate temporary inrush and startup currents without behaving like a fast-acting fuse.
• Indicating design – Helps maintenance personnel check fuse status more efficiently during troubleshooting.
• Dual-element construction – Provides the operating characteristics associated with this time-delay fuse family.
• Class RK5 fuse – Makes the fuse class easy to identify when matching an existing fuse or equipment specification.
• Knife-blade configuration – Intended for compatible fuse blocks, clips, and holders.

Material Compliance and Certifications

The supplied manufacturer information identifies the FLSR225-ID as a Class RK5 fuse. However, catalog-specific UL, CSA, RoHS, or other certification and material compliance declarations were not included in the information provided for this specific part number.

Where It Works Best

The FLSR225-ID makes sense for electrical equipment that specifically calls for a 225A, 600V AC Class RK5 time-delay fuse with an indicating feature. Its time-delay characteristic is particularly useful in properly specified applications where normal startup or operation can produce a brief increase in current. Those short-duration current increases aren't necessarily faults, so having the correct fuse opening characteristic matters.
