KLU-1800 - 1800Amp Fuse Description
KLU-1800 - 1800Amp Fuse
The KLU-1800 is a 1800A Class L fuse for your electrical equipment that requires a 600V fuse with high interrupting capability and a bolted connection. Manufacturer specifications give it a 200 kAIC interrupt rating at 600VAC and a 5-second response time at 500% of rated current. Rather than using a clip-style connection, this fuse has bolted blade ends on both sides and installs with bolts, so checking the physical mounting arrangement is as important as matching the amperage.
Key Features and Benefits
- 1800A current rating for equipment specifically requiring this Class L amperage.
- 600V voltage rating provides a clear electrical parameter for replacement and equipment-matching decisions.
- Class L fuse design is an important compatibility point and should match the equipment requirements.
- Rated with a 5-second response time at 500% of the fuse's current rating.
- The bolted blade-to-bolted blade connection provides a clearly defined physical connection style.
- Bolt mounting helps distinguish the KLU-1800 from fuses intended for clip or holder arrangements.
- Manufacturer-listed product weight is 8.3 lb.
- RoHS compliant according to the supplied manufacturer data.
- CE marked, providing another documented compliance characteristic.

Material Compliance and Certifications
The supplied product information specifically identifies the KLU-1800 as RoHS compliant and CE marked. Those are the documented compliance characteristics provided for this catalog number.
Where It Works Best
The KLU-1800 suits electrical equipment designed for an 1800A Class L fuse rated at 600V, where the manufacturer's 200 kAIC at 600VAC interrupt rating and 5-second response time at 500% meet the equipment's protection requirements.
Installation compatibility deserves equal attention. The equipment must accommodate the bolted blade-to-blade connection, bolt mounting method, and the fuse's 3.5 x 3.5 x 1.75-inch dimensions. If indicator functionality is required, confirm it separately, as the supplied manufacturer information contains conflicting entries.
