FAQs
Plan for ferrule-end terminations with a 1.5 inch length, ensure clearance for a 600 V rated device, and verify that the mounting supports a Class CC fuse module. The KTK-R-3/4 is designed for secure, vibration-resistant connections and straightforward panel integration in industrial cabinets.
The dual-element current-limiting design provides rapid fault clearing while tolerating short-lived inrush, reducing nuisance trips during startup or capacitor discharge. This translates to smoother operation of loads like lighting and motors and improves overall panel reliability.
Yes. With a 0.75 A rating, 600 V capability, and 200 kAIC interrupt rating, it provides robust protection for lighting feeders and distribution circuits, while the rejection-style ferrule ends simplify installation and reduce mis-wiring risks in outdoor and semi-outdoor environments.
The KTK-R-3/4 carries UL Listed and CSA Certified marks, along with RoHS compliance and CE marking. These certifications support compliance with safety, environmental, and regional requirements across North America and Europe.
Track fault events with the time-current curve, replace immediately after a trip to prevent cascading faults, and maintain an appropriate spare fuse inventory. The KTK-R-3/4's reliability and predictable response help reduce downtime and inventory costs in distributed control systems.
