FAQs
KLM-1/4 fuses are designed for standard fuse mounting in control panels. Ensure proper thermal clearance and secure endcaps, with a compatible holder. The device uses a Melamine tube and nickel-plated bronze endcaps for durability. Verify correct amperage rating of 0.25 A and the dual voltage capability (600 Vac / 600 Vdc) to match the circuit requirements and prevent nuisance trips.
The KLM-1/4 is rated for 0.25 A with an interrupt rating of 100 kAIC at 600 Vac and 50 kAIC at 600 Vdc. It supports a voltage rating of 600 Vac and 600 Vdc, making it suitable for both AC control circuits and DC photovoltaic/non-grid applications while protecting sensitive electronics from short circuits.
Yes. The KLM-1/4 is well-suited for DC photovoltaic systems, providing fast-acting protection to DC control circuits and PV arrays. Its 600 Vdc rating and high interrupt capability help safeguard string inverters, combiner boxes, and racking electronics, reducing the risk of cascade failures and downtime in solar installations.
The KLM-1/4 is RoHS compliant and CE marked, ensuring regulatory alignment for broader market deployment. This simplifies cross-border procurement and adherence to environmental and safety requirements in industrial automation, electrical protection, and solar energy projects.
Choosing the KLM-1/4 provides precise protection for small DC control circuits with high reliability thanks to robust interrupt ratings. It reduces downtime, supports global compliance, and simplifies stocking with a standard Eaton Bussmann part. The result is lower total cost of ownership and smoother maintenance across automation and PV systems.
