Eaton KLM-7 Fuse - 50 kAIC at 600 Vdc
Part Number: KLM-7
Quick Summary
KLM-7 fuse provides fast-acting DC protection for control circuits and photovoltaic installations. Engineers often struggle to protect DC control lines while meeting 600 V ratings without frequent nuisance trips. CE Marked and RoHS Compliant, this device supports regulatory alignment and streamlined supplier qualification. Its 7 A rating and high interrupt capability offer reliable protection in industrial power layouts, while durable construction—nickel-plated endcaps and a melamine tube—facilitates long-term service in harsh environments. For panel builders and OEMs, the KLM-7 simplifies sourcing across DC control and PV applications, delivering consistent performance and lower total cost of ownership.

FAQs
The KLM-7 is a 7 A fuse rated for 600 V in both DC and AC applications, making it suitable for DC control circuits and PV string protection. Its high interrupt rating ensures robust fault current handling, while its non-indicating design simplifies replacement in standard control panels.
KLM-7 provides 50 kAIC at 600 Vdc and 100 kAIC at 600 Vac, enabling effective interruption of high-energy faults in DC control lines and AC interfaces. This protects transformers, inverters, and drives from catastrophic damage and reduces downstream downtime.
Yes. The KLM-7 carries CE marking and RoHS compliance, ensuring regulatory alignment for EU markets and support for eco-friendly, restricted-substance policies in industrial procurement.
Install in standard panel cutouts using the melamine tube with nickel-plated bronze endcaps for robust terminations. The fuse is non-indicating and ships in standard packaging, enabling quick replacement during maintenance without special tools.
Choosing the KLM-7 enables reliable protection of DC control circuits with high fault current tolerance, regulatory compliance, and simplified sourcing. This translates to reduced mean time to repair, lower risk of inverter damage, and a lower total cost of ownership in PV and industrial automation deployments.
