KLLU2000 - 2000Amp Fuse

KLLU2000 - 2000Amp Fuse

At 2000 amps, choosing the right fuse means looking well beyond the number printed on the label. The KLLU2000 is a 2000A Class L time-delay, current-limiting fuse in a bolt-in configuration for electrical equipment that requires this specific combination of current capacity, fuse class, voltage, and operating characteristics. The manufacturer identifies the KLLU Series as UL Listed and states that it meets or exceeds UL requirements for Class L fuses. When you're replacing an existing fuse, confirm the complete specification—2000A rating, Class L configuration, time-delay characteristics, AC/DC voltage ratings, interrupting capacity, and bolt-in mounting—rather than selecting by amperage alone.

Key Features and Benefits

• 2000A continuous current rating for equipment specifically designed around a 2000-amp Class L fuse.
• Class L configuration gives technicians and buyers a defined fuse class to match during replacement.
• The time-delay opening characteristic suits circuits that need to accommodate temporary startup current.
• Provides a minimum 10-second time delay at 500% of rated current, according to the manufacturer's KLLU Series specifications.
• Current-limiting design helps reduce short-circuit damage to electrical systems and equipment.
• Rated for operation up to 600VAC.
• Bolt-in construction provides a defined mounting arrangement for compatible equipment.
• Match the non-indicating design when the application requires this configuration.

Material Compliance and Certifications

The manufacturer identifies the KLLU Series as UL Listed and states that these fuses meet or exceed UL requirements for Class L fuses. For the KLLU2000, the supplied specifications also identify a Class L, current-limiting, time-delay fuse with bolt-in construction and the electrical ratings shown above.

Where It Works Best

The KLLU2000 suits electrical equipment that requires a 2000A Class L time-delay, current-limiting fuse with bolt-in mounting. The manufacturer's application guidance includes motor branch-circuit protection, and the KLLU Series time-delay characteristic is designed to handle the heavy starting currents of large motors and other inductive loads.
