FAQs
Install the KTU-700 by aligning the bolt mounting holes and securing the bolted blade ends with appropriate torque on the mounting hardware. Use the standard Bussmann family layout and ensure adequate clearance for expansion and cooling. Confirm proper orientation and holder fit within the panel, then perform a continuity check before energizing.
KTU-700 is rated for 700 A continuous, 600 V nominal, with a 200 kAIC short-circuit interrupt rating at 600 V. It’s a Class L, fast-acting, current-limiting fuse with bolted blade ends and non-indicating status. This combination provides robust fault protection and short-circuit energy control for large feeders, while simplifying coordination with upstream protection devices.
Yes. With a 700 A rating and 200 kAIC interrupt rating, the KTU-700 supports motor feeders and distribution circuits. The Class L design minimizes fault energy, enhancing protection for motors and drive systems. It is well-suited for OEM panel builds and machine control cabinets requiring reliable, scalable protection.
The KTU-700 is CE marked and RoHS compliant, ensuring global regulatory alignment for installations in European and RoHS-restricted markets. These certifications assist with audits, product approvals, and ongoing compliance across multinational manufacturing sites.
Using the KTU-700 within the Bussmann family provides interchangeability with other KTU fuses, standard packaging, and common end-blade geometry. This simplifies stocking, reduces spare parts variety, and accelerates commissioning across multiple panels and facilities while maintaining consistent protection performance.
