KLU-650 - 650Amp Fuse

KLU-650 - 650Amp Fuse

The KLU-650 is a 650A Class L fuse rated for 600V, with a manufacturer-specified 200 kAIC interrupt rating at 600VAC. For anyone replacing an existing fuse, those numbers matter—but so do the details that are easy to miss. In other words, don't choose a replacement on the 650A label alone; verify the Class L configuration, voltage, interrupt rating, response specification, connection style, mounting, and physical dimensions against your equipment requirements.

Key Features and Benefits

• 650A current rating for equipment specifically designed around this Class L fuse rating.
• Rated for 600V operation according to the supplied manufacturer specifications.
• The Class L fuse configuration distinguishes the KLU-650 from fuses that may share similar amperage or voltage ratings but use a different class.
• The manufacturer specifies a 5-second response time at 500% of rated current.
• The bolted blade-to-bolted blade connection provides the defined terminal arrangement for this catalog number.
• Uses a bolt mounting method, an important physical requirement when confirming replacement compatibility.
• Non-indicating design is consistently identified in both the fuse-indicator and special-features fields.
• RoHS compliant, as confirmed in the supplied product data.
• CE marked according to the manufacturer's specifications.
• UPC 051712135030 provides an additional identifier for distinguishing the exact product.

Material Compliance and Certifications

The supplied manufacturer information specifically identifies the KLU-650 as RoHS compliant and CE marked. Those are the material-compliance and marking details provided for this catalog number.

Where It Works Best

The KLU-650 suits electrical equipment designed to use a 650A, 600V Class L fuse with a 200 kAIC interrupt rating at 600VAC and the corresponding bolted-blade, bolt-mount configuration. Also check its manufacturer-specified 5-second response time at 500% against the equipment's fuse requirements, rather than treating it as interchangeable with a fuse with a different response characteristic.
