JLLS175 - 175Amp Fuse

JLLS175 - 175Amp Fuse

When your application calls for 175 amps, Class T, and knife-blade construction, the Littelfuse JLLS175 provides precise specifications to match your equipment. In other words, you don't have to make a decision based on appearance or amperage alone—you have a complete set of electrical and physical characteristics to compare. It's built to last, but proper selection still depends on confirming that those specifications match your equipment's requirements.

Key Features and Benefits

• 175A continuous current rating: Clearly identifies the amperage for equipment specifically requiring a 175-amp fuse.
• Class T configuration: Provides a critical compatibility detail when matching the JLLS175 to existing electrical equipment.
• Fast-Acting (F): The manufacturer specifies a fast-acting opening characteristic.
• Current limiting: The JLLS175 belongs to Littelfuse's current-limiting fuse family.
• Knife-blade-style construction: Makes the physical format easier to identify during compatibility checks.
• Knife-Blade/Bolt-In size: Adds another useful fit-related specification to verify before installation.
• Non-indicating design: Littelfuse specifies the JLLS175 as non-indicating.

Material Compliance and Certifications

The manufacturer specifications supplied for the JLLS175 did not include specific UL, CSA, CE, RoHS, REACH, or other material-compliance or certification information. This should not be interpreted as meaning that the fuse does not carry a particular certification or compliance status. When a listing, approval, or material requirement is necessary for the application, confirm the product markings and consult current authoritative Littelfuse documentation.

Where It Works Best

The Littelfuse JLLS175 175A Class T fuse is best suited to compatible electrical equipment that specifically requires a 175-amp, fast-acting, current-limiting Class T fuse with knife-blade-style construction. It's a particularly clear match to investigate when the equipment specification also calls for a Knife-Blade/Bolt-In configuration, a maximum rating of 600VAC and/or 300VDC, and the corresponding interrupting capacity. The Fuse Block/Clip/Holder mounting method and LFT60200 Series PG holder provide additional details to confirm the intended configuration.
