FAQs
The KLM-12 uses ferrule end x ferrule end connections, making it compatible with standard Bussmann series and common ferrule-terminal fuse holders found in industrial control panels, motor control centers, and distribution blocks. Always verify terminal size and mounting fitment for secure, vibration-resistant installation in your enclosure.
The KLM-12 is a 12 A fuse rated for 600 Vac and 600 Vdc. It provides an interrupt rating of 100 kAIC at 600 Vac and 50 kAIC at 600 Vdc, with non-indicating operation and ferrule-end connections, ensuring reliable disconnection under fault conditions and straightforward maintenance.
Yes. The KLM-12 is CE marked and RoHS compliant, aligning with European regulatory requirements and minimizing compliance risk for electrical protection assemblies in machinery, process equipment, and panel systems.
Its non-indicating design reduces visual inspection requirements, while the ferrule-end construction and standard packaging streamline field replacements. Coupled with wide availability through Eaton’s Bussmann series catalogs, this fuse lowers stocking complexity and accelerates mean time to repair in high-demand maintenance environments.
Follow manufacturer torque guidelines for ferrule-terminals, inspect endcaps and the Melamine tube for signs of wear, and replace only with the same model to preserve interrupt ratings. Verify polarity and ensure secure seating in compatible fuse holders to prevent arcing and ensure safe disconnection under fault conditions.
