FLSR030 - 30 Amp Fuse

FLSR030 - 30 Amp Fuse

When an electrical circuit must handle the brief current surge that accompanies equipment startup, a standard fast-acting fuse isn't always the right fit. The FLSR030 is a 30-amp, 600V Class RK5 time-delay fuse built for applications where temporary inrush current is part of normal operation. Whether you're maintaining motor equipment, machinery, transformers, or electrical distribution equipment, the FLSR030 is a practical choice when the application specifically calls for a 30A Class RK5 time-delay fuse.

Key Features and Benefits

• 30 amp rating for circuits designed around 30A overcurrent protection.
• Class RK5 construction for equipment requiring this specific fuse class.
• Handles applications up to 600 VAC or 300 VDC.
• Dual-element time-delay design helps prevent unnecessary fuse operation during brief startup surges.
• Slo-Blo characteristics make it particularly useful around equipment with normal inrush current.
• Industrial cartridge format fits compatible fuse blocks, clips, and holders.
• Non-indicating construction keeps the design simple.

Material Compliance and Certifications

The manufacturer identifies the FLSR030 as a Class RK5 fuse. The product information provided does not specify individual material declarations or detailed information on RoHS, REACH, or agency certifications. If your application requires specific approval or material compliance standards, confirm these requirements against the current documentation for the exact FLSR030 catalog number.

Where It Works Best

The FLSR030 makes sense in circuits where brief current surges are expected, but sustained overloads still need dependable protection. Motor applications are a good example. A motor can draw considerably more current when it first starts than when it's running. The time-delay characteristics of the FLSR030 enable it to tolerate these short-startup conditions without unnecessarily opening the circuit.

It's also suited to compatible industrial machinery, transformer circuits, control equipment, feeders, and electrical distribution systems designed for Class RK5 protection. The combination of a 30A rating, dual-element construction, and time-delay operation makes it especially useful where nuisance fuse openings caused by normal inrush current need to be minimized.
