FLNR150-ID - 150 Amp Fuse

FLNR150-ID - 150 Amp Fuse

When a circuit calls for a 150A Class RK5 time-delay fuse, the FLNR150-ID provides the protection you need, along with a handy indicating feature that can make troubleshooting a little easier. This dual-element fuse is rated for 250 VAC and 125 VDC and uses a Slo-Blo/time-delay design. That delay is significant in applications where brief current surges are part of normal operation—you don't necessarily want a fuse opening every time equipment starts up. When you're inspecting equipment or tracking down a problem, being able to identify fuse status more easily can save valuable time.

Key Features and Benefits

• 150-amp rating for applications requiring 150A overcurrent protection.
• Class RK5 design for equipment and circuits specified for this fuse class.
• Time-delay / Slo-Blo operation helps accommodate temporary startup and inrush currents.
• Dual-element construction provides the time-delay characteristics needed in applications where short current surges are normal.
• Built-in indication makes fuse status easier to identify during maintenance and troubleshooting.
• Rated for a maximum of 250VAC and 125VDC.
• Knife-blade design fits compatible fuse blocks, clips, and holders.
• High interrupting ratings protect demanding electrical applications.

Material Compliance and Certifications

The FLNR150-ID is a Class RK5 fuse. The supplied product information does not provide sufficient detail to make specific claims regarding RoHS, REACH, lead-free status, or other material compliance declarations. When one of these requirements applies to a particular project or facility, the documentation for the exact FLNR150-ID catalog number should be checked before installation.

Where It Works Best

The FLNR150-ID makes the most sense in industrial and commercial applications that specifically require a 150A Class RK5 time-delay fuse. It's particularly useful when equipment experiences a normal current surge during startup. The time-delay design allows for that brief inrush, rather than treating every temporary increase in current as a condition requiring the fuse to open.

That makes this fuse style useful for properly specified motor circuits, transformers, industrial machinery, control equipment, and electrical distribution applications. The indicating feature is a nice practical touch, too. In a busy facility, anything that helps maintenance personnel identify fuse status more quickly can make troubleshooting less tedious.
