FLSR150-ID - 150Amp Fuse

FLSR150-ID - 150Amp Fuse

Need a 150A Class RK5 fuse that can handle normal, short-duration current surges without opening unnecessarily? The FLSR150-ID is a 600V AC / 300V DC indicating time-delay fuse with dual-element construction and Slo-Blo operation. With its 150-amp continuous rating, Class RK5 configuration, knife-blade construction, and time-delay characteristics, this fuse is a solid replacement choice when those specifications match the equipment you're servicing.

Key Features and Benefits

• 150A continuous current rating – Made for applications requiring a 150-amp Class RK5 fuse.
• Rated up to 600V AC – Suitable for compatible AC electrical systems within this voltage rating.
• Rated up to 300V DC – Can also be used in properly specified DC applications.
• Indicating fuse – Helps maintenance personnel identify fuse status during inspection and troubleshooting.
• Time-delay / Slo-Blo operation – Handles acceptable short-duration inrush currents without reacting like a fast-acting fuse.
• Dual-element construction – Provides the time-delay characteristics associated with the FLSR_ID series.
• Class RK5 fuse – Makes it easier to match equipment specifically calling for an RK5 fuse.
• Knife-blade construction – Fits compatible fuse blocks, clips, and holders.

Material Compliance and Certifications

The manufacturer information provided identifies the FLSR150-ID as a Class RK5 fuse. However, the supplied specifications do not provide sufficient information to accurately state the individual UL, CSA, RoHS, or other material compliance certifications for this exact catalog number. If your installation requires a specific approval, listing, or material compliance standard, verify that requirement against the current manufacturer documentation before installation.

Where It Works Best

The FLSR150-ID makes sense when your equipment calls for a 150A, 600V Class RK5 time-delay fuse and temporary inrush current is a normal part of operation. Instead of selecting a fuse simply because "150A" appears on the label, it's important to match the fuse class, voltage rating, time-delay characteristic, interrupting capacity, physical configuration, and indication requirement.

If you're replacing an existing FLSR150-ID, match the complete specifications before returning the equipment to service. Two fuses can share the same 150A rating and still differ in voltage, class, opening characteristics, indication, or interrupting capacity.
