Eaton KLM-2-1/2 Fuse DC/AC Protection - 100 kAIC at 600 Vac
Part Number: KLM-2-1/2
Quick Summary
The KLM-2-1 fuse by Eaton protects DC control circuits and PV systems. For engineers, selecting a fuse that safely handles both DC and AC faults without nuisance trips is a recurring challenge. CE marked and RoHS compliant, it also offers 50 kAIC at 600 Vdc and 100 kAIC at 600 Vac, delivering reliable protection under fault conditions. Its standard packaging, non-indicating operation, and robust endcaps streamline installation in control panels and renewable energy applications, reducing install time and lifecycle cost. In practice, this means confident protection across mixed DC/AC environments while keeping stock, sourcing, and maintenance straightforward.
