Special features
Non-indicating
Feature ferrule design with Class K5 construction enables reliable, quick field replacement, reducing commissioning time and minimizing misalignment risk. Business impact includes lower downtime, simpler maintenance, and consistent protective performance for sensitive Bussmann Edison-style circuits in control panels. Application: ideal for industrial control panels, machine enclosures, and power distribution blocks where fast, predictable protection is essential. Feature 40 A amperage rating with a 10 kAIC interrupt capability provides strong short-circuit protection against high-energy faults. Business impact is improved equipment safety, reduced risk of collateral damage, and better uptime for drives, motors, and feeders. Application: motor starters, servo drives, and high-inrush loads in manufacturing environments. Feature non-indicating design reduces visual indicators inside enclosures, simplifying installation and panel layout. Business impact includes faster commissioning and cleaner panel aesthetics, with fewer components to monitor during routine maintenance. Application: compact cabinets and high-density panels where spare indicator modules are undesirable. Feature CE Marked and CSA certification visibility reinforces compliance across major markets. Business impact: easier regulatory validation, accelerated procurement, and higher supplier confidence. Application: multinational automation projects and panel builds requiring formal conformity marks. Feature standard packaging and 1-piece quantity simplify stocking and procurement, reducing supply-chain variety and inventory costs. Business impact: lower total cost of ownership, faster replacement cycles, and more predictable maintenance planning. Application: OEMs and panel shops maintaining lean inventories for Edison-style fuses.

FAQs
The KON40 is a ferrule-design Edison fuse rated at 40 A with 250 V and 10 kAIC interrupt. Install it by matching the ferrule size to the panel’s Bussmann Edison fuse holders, ensuring proper alignment with the standard packaging and one-piece quantity. Typical installations are in industrial control panels, feeders, and machine enclosures where a compact, standard fuse solution is required.
KON40 provides a 40 A amperage rating, 250 V voltage rating, and a 10 kAIC interrupt rating. This combination protects moderate to high inrush loads such as motor starters, drives, and power distribution feeders in industrial environments, reducing the risk of damaging downstream equipment during fault events.
Yes, the KON40 carries CE Marking and is CSA Certified per the provided specifications. This supports regulatory compliance in many markets and simplifies procurement for multinational projects, though you should verify local validation scopes for your exact installation.
Class K5 ferrule design offers robust, reliable mounting and alignment within Edison-style fuse blocks, reducing misfit risk during replacement. The result is faster commissioning, fewer field service issues, and consistent protective performance across installed fuses in control panels and power distribution enclosures.
Stocking KON40 fuses provides a lean, standardized solution with 1-piece packaging for easy inventory control. The non-indicating design keeps panel interiors uncluttered, while CE and CSA certifications support cross-market deployments. This combination lowers total cost of ownership and speeds maintenance cycles for industrial automation projects.
