Eaton KON400 Fuse - Knife Blade, 400 A, 10 kAIC, CE Marked
Part Number: KON400
Quick Summary
KON400 fuse from Eaton delivers high-current protection for electrical panels and switchgear. Engineers often struggle with fuses that trip unpredictably or fail to indicate status during maintenance; KON400 addresses this with clear ratings and a robust 400 A capacity. This part carries CE Marking and aligns with CSA certification considerations, with Class K5 design and a 10 kAIC interrupt rating for reliable coordination. With standard 8 in length and compact 1x1 in footprint, it integrates easily into existing Eaton Edison lines and reduces downtime. In practice, customers gain safer protection, predictable selectivity, and lower total cost of ownership.

Non-indicating
Feature: Knife blade fuse design provides fast, secure seating in standard fuse blocks. Business impact: Reduces contact resistance wear and improves replacement speed during maintenance windows. Application: Ideal for Eaton Edison panels and motor control centers where reliable, quick swaps matter. Feature: 400 A amperage rating with a 10 kAIC interrupt capability ensures selective protection against high fault currents. Business impact: Limits damage to downstream equipment and minimizes downtime from overcurrent events. Application: Suitable for feeders and main protection in industrial installations requiring robust interrupt performance. Feature: 250 V voltage rating and Class K5 classification align with typical industrial distribution standards. Business impact: Helps ensure coordination with upstream protection devices and compliance with electrical codes. Application: Commonly deployed in low- to medium-voltage commercial and light-industrial circuits. Feature: Non-indicating indicator and standard packaging simplify inventory management and field service. Business impact: Reduces maintenance effort and stock complexity, enabling faster replacements. Application: Works with standard Bussmann/Eaton fuse blocks and field service workflows. Feature: Compact dimensions (8 in length, 1 in width and height) and 1 unit per package support easy integration and transportation. Business impact: Improves installation planning and reduces logistics costs. Application: Suited for retrofit projects and new panel builds in constrained spaces. Industry context: The KON400 line is widely adopted in switchgear and motor control environments where deterministic protection and straightforward sourcing matter for uptime metrics and total cost of ownership.

FAQs
The KON400 is rated for 400 A with an interrupt rating of 10 kAIC, enabling reliable protection against high fault currents. This combination supports selective coordination in medium-to-large electrical distributions and reduces the risk of extensive equipment damage during faults.
Yes, the KON400 carries CE marking for compliance with European safety standards. The specification also lists CSA Certification as a field, though some configurations may note Not Applicable; this highlights applicability depending on regional requirements and documentation. Always verify your regional certification needs before procurement.
The KON400 measures 8 inches in length with a 1 inch width and height, and is packaged Standard with a quantity of one fuse per package. These compact dimensions simplify replacement in constrained panels and ease stock management for field service teams.
KON400 is suited for electrical protection in switchgear, motor control centers, feeders, and distribution panels up to 250 V. Its Class K5 design and 400 A rating make it appropriate for high-current circuits requiring reliable, fast interrupt performance in industrial environments.
With a non-indicating status, standard packaging, and compatibility with common fuse blocks, KON400 simplifies stocking and field replacement. Its robust interrupt rating minimizes downstream damage, contributing to reduced downtime and lower maintenance costs over the equipment’s life.
