JLLN025 - 25Amp Fuse

JLLN025 - 25Amp Fuse

If your equipment calls for a 25-amp Class T fuse, the Littelfuse JLLN025 offers clear specifications to check before installation. This industrial cartridge fuse is fast-acting and current-limiting, with a maximum rating of 300VAC and 160VDC. In other words, you have more than a catalog number—you have concrete electrical and mounting details that make compatibility easier to evaluate. It's a straightforward Littelfuse Class T component built to last when properly selected and used within its specified ratings.

Key Features and Benefits

• 25A continuous current rating — Provides a specific amperage rating to match against the requirements of your equipment.
• Class T fuse — Designed for applications requiring the electrical and physical characteristics of a Class T fuse.
• Fast-acting (F) opening — A clearly defined opening characteristic helps you determine whether the JLLN025 matches the required fuse type.
• Current-limiting design — Littelfuse identifies the JLLN family style as current-limiting.
• 300VAC maximum rating — Suitable for compatible AC applications operating within the specified voltage rating.
• 160VDC maximum rating — Also carries a separate DC voltage specification.
• Non-indicating configuration — Manufacturer specification lists the JLLN025 as non-indicating.

Material Compliance and Certifications

The supplied manufacturer information does not specify UL, CSA, CE, RoHS, REACH, or other certification or material-compliance details for the JLLN025. That does not mean the product lacks any particular certification. If a specific listing, approval, or material-compliance requirement applies to your equipment or project, confirm it using the markings and authoritative documentation for the exact JLLN025 catalog number.

Where It Works Best

The Littelfuse JLLN025 25A Class T fuse is a practical fit for compatible electrical equipment specifically designed around a 25A, fast-acting, current-limiting Class T industrial cartridge fuse. For AC service, confirm that the application aligns with the 300VAC maximum rating and 200 kA interrupting capacity at 300VAC. For DC service, use the separate 160VDC maximum and 50 kA interrupting rating at 160VDC when checking compatibility. The mounting arrangement must also accommodate the specified cartridge format and an appropriate fuse block, clip, or holder.
