FAQs
The KTS-R-12 is designed for RK1-compatible fuse holders rated for 600 V and 12 A. Ensure the holder matches the rejection-style design to prevent incorrect insertions, verify panel clearance and venting, and torque terminals to the manufacturer’s specification. Use only compatible Bussmann RK1 assemblies to maintain 200 kAIC performance and compliance.
Class RK1 is a standardized family within the Bussmann RK fuse line, indicating fast-acting, current-limiting protection suitable for control circuits and motor loads. The KTS-R-12’s 12 A rating and 200 kAIC interrupt rating deliver targeted protection against short circuits, reducing equipment damage and downtime while enabling predictable replacement in common industrial panels.
Yes. The KTS-R-12 is rated for 600 V and provides a 12 A current-limiting protection with a 200 kAIC interrupt rating, making it appropriate for motor starters, control panels, and other 600 V control circuits in manufacturing environments. Its fast-acting behavior minimizes fault energy and preserves downstream components.
The KTS-R-12 is CE Marked, indicating conformity with European safety standards. It is aligned with Class RK1 fuse standards and is RoHS compliant, aligning with restricted-substance requirements. This combination supports global deployment in regulated facilities and simplifies cross-border procurement.
Expect improved uptime due to faster fault clearance and reduced downstream damage from high-energy faults. The 200 kAIC interrupt rating protects feeders and equipment in energy-rich faults, lowering replacement costs. The standard RK1 form factor and non-indicating design streamline stock management and retrofit projects, delivering predictable maintenance planning.
