JLLS150 - 150Amp Fuse

JLLS150 - 150Amp Fuse

The Littelfuse JLLS150 is easy to choose when you know your equipment's exact specifications. This 150-amp Class T fuse combines a fast-acting opening characteristic with a current-limiting design and Knife-Blade/Bolt-In construction. For buyers maintaining compatible electrical equipment, that combination of clearly defined ratings and construction makes identification much more straightforward. It's built to last, and the key to selecting it confidently is making sure every important rating and physical requirement matches your equipment.

Key Features and Benefits

• 150A continuous current rating: Provides the exact amperage specification needed when matching a replacement fuse to equipment requiring 150 amps.
• Class T fuse: Clearly defined fuse class helps you narrow the selection to the configuration specified by your equipment.
• Fast-acting (F) opening: The manufacturer-specified fast-acting characteristic provides another important compatibility checkpoint.
• Current-limiting design: Littelfuse identifies the JLLS150 as part of its current-limiting fuse family.
• Knife-blade-style construction: Helps identify the required physical configuration before installation.
• Knife-Blade/Bolt-In size: Gives maintenance teams and buyers an additional fit-related specification to confirm.
• Non-indicating: Manufacturer data identifies this model as a non-indicating fuse.

Material Compliance and Certifications

The supplied manufacturer specifications for the JLLS150 included no specific UL, CSA, CE, RoHS, REACH, or other certification or material-compliance information. That does not mean the product lacks any particular certification or compliance status. Where a specific listing, approval, or material requirement is important to the application, verify the markings on the product and consult current authoritative Littelfuse documentation.

Where It Works Best

The Littelfuse JLLS150 150A Class T fuse is best suited to compatible electrical equipment that specifically calls for a 150-amp, fast-acting, current-limiting Class T fuse with knife-blade-style construction. It is especially easy to identify when the equipment documentation also specifies a Knife-Blade/Bolt-In configuration, maximum ratings of 600VAC and/or 300VDC, and the corresponding interrupting rating. The Fuse Block/Clip/Holder mounting specification and LFT60200 Series PG holder provide additional checkpoints for confirming suitability.
