FAQs
Power down the equipment and ensure the correct Bussmann holder is used for a Class RK1, single-element fuse. Align the knife-blade contacts with the holder’s terminals, insert until seated, and confirm full engagement is achieved to prevent arcing. Replace only with a KTS-R-4 of the same rating to maintain protection integrity and uptime.
The KTS-R-4 is a Class RK1 fuse, indicating a fast-acting, current-limiting device designed for general purpose protection in low-voltage circuits. It supports motor starters, panelboards, and distribution panels up to 600 V, with a 4 A rating and a 200 kAIC interrupt capacity for high fault tolerance in demanding industrial environments.
The KTS-R-4 is specified for 600 V and is tested for AC operation with a 200 kAIC interrupt rating. For DC applications, consult the data sheet for any DC-specific ratings or derating guidance, and consider selecting a fuse explicitly rated for DC service if required by the installation.
The KTS-R-4 carries CE Marking for compliance with applicable European standards. It is a Class RK1 fuse with a rejection-style design and knife-blade features, aligning with common industrial protection practices and ensuring compatibility with standard Bussmann-series components.
With a 4 A rating and high 200 kAIC interrupt capacity, the KTS-R-4 minimizes fault energy and reduces arc damage during faults, leading to longer component life and lower maintenance downtime. Its compact form and standard packaging simplify stock and rapid replacements, improving overall equipment reliability.
