FAQs
To install the KTU-500, align the knife blade ends with the corresponding fuse holder contacts in the Bussmann Class L panel system. Ensure the holder is rated for 500 A and that the circuit is de-energized before insertion. Use the appropriate torque on any mounting screws and verify seating with a visual check and continuity test per the KTU datasheet No. 1010 recommendations.
The KTU-500 is rated at 500 A. Replacement should occur when the fuse has operated within its intended overcurrent protection without nuisance tripping, or after a fault event that drew near its rating. Always refer to the Bussmann datasheet No. 1010 for the recommended replacement cycle and performance curves to optimize reliability.
The KTU-500 is designed for high-current protection in industrial power distribution, typically within AC environments. For DC applications, confirm the specific operating conditions and interrupting ratings in the official Bussmann data sheet No. 1010 and consult Eaton technical support to ensure compatibility with your DC system and safety requirements.
The KTU-500 features RoHS compliance, aligning with restricted-substances requirements. CE/UL listings and other regional certifications may not be specified in the provided data and should be confirmed with Eaton for your region and application. Always verify current certifications via the Eaton documentation and rohs tool when planning global deployments.
The knife blade design enables faster, tool-free replacement, reducing downtime during routine maintenance or fault isolation. Its 500 A rating supports robust protection for high-current loads, potentially lowering arc-related damage costs. Combined with thorough documentation, this fuse helps lower spares inventory and speeds engineering validation, delivering measurable lifecycle and uptime improvements.
