Special features
Non-indicating
Feature → Business Impact → Application: The KON300 delivers a 300 A amperage rating, which provides robust protection for high-current feeder circuits, reducing the risk of equipment damage and unplanned downtime in motors, drives, and panel feeders. This translates to improved line uptime and lower risk of costly outages in manufacturing environments. Feature → Business Impact → Application: Its 10 kAIC interrupt rating enables rapid fault clearing under high fault currents, minimizing arc energy and downstream damage, a critical benefit for panels in metalworking, packaging, and process plants where faults can spike quickly. Feature → Business Impact → Application: A 250 V voltage rating covers common industrial control and power distribution applications, ensuring compatibility with standard 3-phase systems and 120/240 V control circuits, which simplifies design and reduces sourcing complexity. Feature → Business Impact → Application: Knife-blade Edison KON mounting and non-indicating operation enable fast, tool-free fuse replacement with minimal panel downtime, ideal for assembly lines and critical process lines that demand quick maintenance windows. Feature → Business Impact → Application: Class K5 construction with standard packaging and a 1-pack configuration streamline stocking and procurement for maintenance teams, delivering predictable lead times and reduced inventory costs in large facilities. Feature → Business Impact → Application: The CE Marking and inherent safety design support compliance across multiple regions, helping engineering teams meet regulatory requirements while focusing on throughput and operational efficiency.

FAQs
The KON300 uses a knife-blade design for quick, tool-free replacement in Edison-style fuse holders. Ensure the holder is rated for 300 A and 250 V and align the blade orientation with the holder’s contact springs. Verify the panel is de-energized before replacement and replace only with the same model KON300 to maintain the 10 kAIC interrupt rating and Class K5 classification.
Key specifications include a 300 A amperage rating, 10 kAIC interrupt rating, and a 250 V voltage rating. These metrics define the fuse’s capability to interrupt fault currents safely and protect downstream equipment in typical industrial power distributions and control circuits.
Yes, KON300 is designed for 250 V systems and is well-suited for high-current feeders, motor control centers, and critical process lines where fast fault clearing and reliable protection are required. Its Class K5 rating supports standardized protection schemes, while the knife-blade design aids fast replacements in busy facilities.
KON300 is CE Marked, indicating compliance with European safety standards. The datasheet lists CSA certification status as Not Applicable in some contexts. When sourcing for regulatory environments outside Europe, verify regional requirements and ensure the fuse pairing and panel protections meet local electrical codes.
The non-indicating, standard-packaged KON300 reduces nuisance signals and simplifies stock management, lowering maintenance overhead. Its fast replacement with knife-blade design minimizes downtime in production lines, contributing to shorter mean time to repair (MTTR) and improved total cost of ownership for protection systems in factories and process plants.
