FAQs
Yes. The KTU-801 uses bolt mounting with ferrule design suitable for standard electrical panels and MCC enclosures. Its robust mechanical footprint simplifies field assembly, reduces wiring complexity, and supports secure, vibration-resistant installations in industrial environments.
The fuse provides 801 A amperage rating, 600 V voltage rating, and a 200 kAIC interrupt rating at 600 VAC. These specs enable proper coordination with upstream protection while safeguarding downstream circuits from high-energy faults, helping minimize damage and downtime.
Typical applications include motor control centers, power distribution panels, and industrial automation equipment in manufacturing, processing, and packaging lines. The Class L, current-limiting characteristics are well-suited for high-current feeds and critical loads requiring fast fault isolation.
The KTU-801 is CE marked and RoHS compliant, aligning with European regulatory requirements and environmental guidelines. This ensures regulatory readiness for global deployments and reduces compliance overhead during audits and integrations.
By delivering fast, reliable fault isolation and limiting energy during faults, the KTU-801 reduces collateral damage to downstream devices and minimizes downtime. Its durable construction and standardized Bussmann series design also lower replacement frequency and simplify parts stocking for maintenance teams.
