JLLS050 - 50Amp Fuse

JLLS050 - 50Amp Fuse

When your equipment calls for a 50-amp Class T fuse, matching the full specification is the smart way to find the right part. The Littelfuse JLLS050 combines a 50A continuous current rating with fast-acting operation, current-limiting characteristics, and industrial cartridge construction.

Key Features and Benefits

• 50A continuous current rating: Clearly identifies the amperage for equipment specifically requiring a 50-amp fuse.
• Class T fuse: Provides an important compatibility specification when matching the JLLS050 to existing electrical equipment.
• Fast-acting opening: Littelfuse specifies the opening characteristic as Fast-Acting (F).
• Current-limiting characteristics: Identified by the manufacturer as part of the current-limiting family style.
• 600VAC maximum voltage: Supports compatible AC applications operating within the fuse's specified electrical ratings.
• 300VDC maximum voltage: Provides a clearly defined rating for compatible DC applications.
• Industrial cartridge construction: Offers a defined physical configuration that can be checked against the equipment and fuse holder.
• Non-indicating configuration: The JLLS050 does not include an indicating function.

Material Compliance and Certifications

The manufacturer specifications supplied for the JLLS050 did not include specific UL, CSA, CE, RoHS, REACH, or other certification or material-compliance information. That does not establish that the fuse lacks any particular certification or compliance status. If an installation requires a specific approval or material standard, verify the product markings and current authoritative manufacturer documentation before use.

Where It Works Best

The Littelfuse JLLS050 50A fuse is a suitable choice for compatible electrical equipment specifically requiring a 50A, fast-acting, current-limiting Class T industrial cartridge fuse with the stated electrical characteristics. It is particularly straightforward to identify when existing equipment documentation calls for JLLS050 or specifies the same combination of fuse class, amperage, opening characteristic, voltage ratings, interrupting ratings, construction, and mounting requirements.
