FAQs
The LCU1000 uses a standard bolt mounting method for straightforward installation in compatible panels. Ensure the fuse is seated securely in the holder, that mounting hardware is tightened to the enclosure’s specifications, and that the circuit is de-energized prior to installation. This approach minimizes vibration issues and ensures reliable electrical contact.
The LCU1000 provides a 200 kAIC interrupt rating, meaning it can safely interrupt fault currents up to 200 kiloamperes. This level of protection is critical in heavy-duty power distribution to prevent equipment damage, reduce downtime, and improve overall system reliability during high-energy fault events.
Yes, the LCU1000 is RoHS compliant. This indicates that the fuse meets regulatory limits on hazardous substances, supporting safer and more sustainable manufacturing and end-of-life handling, and simplifying compliance for projects with strict environmental requirements.
The LCU1000 is UL Listed and CSA Certified, providing recognized safety and performance validation. These certifications reduce procurement risk, ease supplier qualification, and help meet regulatory and customer requirements for industrial electrical protection in North American and global markets.
Typical applications include main feeders in industrial power distribution, motor control centers, and large panel boards where high current protection is needed without nuisance-level indicators. The 600 V rating and high interrupt capacity make it suitable for demanding environments such as manufacturing, water treatment, and energy-intensive processes.
