Eaton KLM-1 Fuse - 50 kAIC at 600 Vdc, CE RoHS
Part Number: KLM-1
Quick Summary
The Eaton KLM-1 fuse is a compact DC control circuit fuse designed for DC photovoltaic and industrial control applications. Design engineers often struggle with incorrect ratings, nuisance opening, and slow fault isolation in tight DC power installations. This device is CE-marked and RoHS compliant, supporting European regulatory requirements while delivering robust 600 V ratings. For procurement and maintenance teams, the non-indicating indicator reduces nuisance trips, and the ferrule-end connections simplify installation in control cabinets. With a 1 A rating and 50 kAIC interrupt capability at 600 Vdc (and 100 kAIC at 600 Vac), it provides reliable protection across DC control circuits and PV systems.

Datasheet - FNQ-30
Feature: Compact Melamine tube construction with nickel-plated bronze endcaps and ferrule-end terminals reduces panel footprint while ensuring durable, vibration-resistant connections in harsh industrial environments. Business Impact: Frees cabinet space, minimizes contact resistance, and lowers replacement risk in demanding settings. Application: Ideal for DC control circuits and PV string protection in automation racks and solar installations. Feature: 1 A nominal rating delivers predictable protection for low-current control circuits. Business Impact: Minimizes nuisance trips and unplanned downtime in automation equipment, enabling steadier line uptime. Application: Suitable for small DC control loads in conveyor systems and machine enclosures. Feature: High interrupt ratings of 50 kAIC at 600 Vdc and 100 kAIC at 600 Vac enable fast fault clearance. Business Impact: Improves safety margins and improves feeder selectivity in mixed DC/AC networks. Application: Recommended for protection blocks near PV inverters and DC bus segments in industrial plants. Feature: Non-indicating status and RoHS CE compliance streamline maintenance and regulatory readiness. Business Impact: Reduces ongoing inspection requirements and accelerates European project approvals. Application: Supports European automation cabinets and energy-management systems with straightforward compliance. Feature: Ferrule end x ferrule end connections with standard packaging ensure quick, reliable installation. Business Impact: Lowers installation time and inventory complexity for spare parts. Application: Interchangeable with Bussmann series lines in service-heavy DC protection schemes.

FAQs
The KLM-1 uses ferrule end x ferrule end terminations, which provide reliable, vibration-resistant connections suitable for control cabinets and PV DC buses. Installation is straightforward with standard crimp ferrules, reducing time spent on termination prep and ensuring consistent contact quality in industrial environments.
KLM-1 is rated at 1 A with an interrupt rating of 50 kAIC at 600 Vdc and 100 kAIC at 600 Vac. The voltage rating is 600 Vac and 600 Vdc, making it suitable for both AC and DC protection in mixed systems. This enables fast fault clearance and protection for sensitive DC control circuits and PV arrays.
Yes. The KLM-1 is designed for DC control circuits and PV systems, offering 1 A protection with high interrupt capabilities. Its ferrule-end connections and durable construction support reliable protection in solar inverters, DC buses, and automation cabinets, while CE RoHS compliance ensures regulatory alignment in solar and industrial facilities.
The KLM-1 is CE marked and RoHS compliant, ensuring conformity with European regulatory requirements for electrical safety and hazardous substances. While not specified for SIL or IP ratings in the provided data, these certifications support global procurement and project approvals in European markets and beyond.
With a non-indicating fuse indicator, the KLM-1 reduces nuisance trips and maintenance checks in routine inspections. The ferrule-end terminations and nickel-plated bronze endcaps contribute to durable contact reliability, lowering replacement frequency in service-heavy DC control panels and PV installations, and simplifying stock management for spare parts.
