FAQs
The KOS100 is a knife-blade fuse designed for Edison/KOS fuse blocks. Ensure the panel accepts Class K5 fuses and that the mounting space accommodates the 7 inch length with a 1 by 1 inch footprint. Power down the system, verify voltage, insert firmly into the fuse holder, and close the block to complete the connection. Use the standard packaging (five per pack) to simplify stocking.
The KOS100 provides a 100 A amperage rating, a 600 V voltage rating, and a 10 kAIC interrupt rating. These ratings support protection for medium to high-current circuits and motor loads in industrial environments, ensuring rapid fault isolation while maintaining system continuity for non-fault events.
Yes. With 100 A, 600 V, and 10 kAIC, the KOS100 is well-suited for motor control centers and automation cabinets where dependable overcurrent protection is essential. Its Class K5 construction and compact dimensions help fit standard MCC enclosures, while the non-indicating design supports straightforward replacement in controlled environments.
The KOS100 is CE marked and CSA certified, signaling compliance with European and North American safety standards. These certifications help mitigate regulatory risk for global deployments, support supplier qualification, and simplify auditing during audits and commissioning of electrical protection schemes.
The KOS100 supports reliable protection with a high interrupt rating and standard packaging, enabling predictable maintenance planning and streamlined procurement. While the catalog notes no warranty, the ability to stock five per package and the rapid replacement capability reduce downtime costs and help maintain consistent production throughput over time.
