KLU-1200 - 1200Amp Fuse

KLU-1200 - 1200Amp Fuse

When replacing a KLU-1200 fuse, the 1200A rating may be the first thing you notice, but the details around it determine whether you have the right match. The KLU-1200 is a 1200-amp Class L fuse rated at 600V, with a manufacturer-specified 200 kAIC interrupt rating at 600VAC and a 5-second response time at 500% of rated current. When checking a replacement, compare the fuse class, voltage, interrupt rating, response characteristics, connection style, mounting method, and dimensions against the equipment requirements before matching.

Key Features and Benefits

• 1200A current rating for equipment specifically designed around this amperage and fuse class.
• Class L configuration provides an important compatibility point when identifying a replacement fuse.
• Rated for operation at 600V.
• Manufacturer specifies a 5-second response time at 500% of the fuse's rated current.
• The bolted blade-to-bolted blade connection design matches the defined physical connection arrangement for the KLU-1200.
• Uses a bolt-mounting method; confirm this detail when replacing an existing fuse.
• Non-indicating design is confirmed in both the manufacturer's fuse-indicator and special-features fields.
• RoHS compliant, according to the supplied manufacturer compliance information.
• CE marked as documented in the supplied specifications.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLU-1200 as RoHS-compliant and CE-marked. These are the specific compliance and marking statements documented for this catalog number.

Where It Works Best

The KLU-1200 is best matched with electrical equipment designed for a 1200A Class L fuse and its corresponding electrical and physical requirements. For AC service, confirm that the equipment requirements match the fuse's 600V rating and 200 kAIC interrupt rating at 600VAC. Also consider the specified 5-second response time at 500% when matching the fuse's response characteristics to the equipment.
