The 500 A amperage rating paired with a 200 kAIC interrupt rating enables rapid fault isolation, guarding transformers, feeders, and downstream circuits from high-energy surges. By clearing faults swiftly, it minimizes arc energy and reduces downtime, translating into lower maintenance costs and higher process uptime. Industries such as chemical processing, oil and gas, and manufacturing rely on this reliability in feeders, switchgear, and distribution panels.Class RK1 and non-indicating design contribute to reliability and ease of use. RK1 selection allows coordination with other fuses and protective devices, helping prevent nuisance trips in complex protection schemes. The non-indicating format keeps panel interiors uncluttered, simplifying visual inspection and reducing calibration overhead during routine maintenance.Glass-melamine tube construction provides durable insulation and arc-quenching performance in harsh environments. The operating temperature range of -40° to 85°C and a 250 V rating support dependable protection across wide industrial conditions, from refrigerated facilities to hot process areas. This combination reduces replacement frequency and extends service intervals for critical lines.Certifications including CE Marked, UL Listed, and CSA Certified support multi-region compliance and supplier qualification. These credentials simplify international procurement, streamline audits, and reduce risk when specifying components for global projects. Compatibility with Eaton Edison lines and standard fuse blocks improves installation efficiency and reduces the need for special SKUs or custom parts.Stocking and maintenance are straightforward with standard packaging and a quantity of one per package. The 10.38-inch length, 2.88-inch width and 2.88-inch height fit common enclosures, while the standard packaging type speeds reorder cycles and inventory planning. Overall, NCLR500 offers lifecycle cost benefits in medium to high-current protection schemes.

FAQs
NCLR500 is designed for compatibility with standard Edison fuse blocks used in industrial panels and switchgear. It operates at 250 V and fits typical mounting footprints found in control cabinets. The packaging and form factor support straightforward stocking, with a single-unit quantity per order to simplify maintenance scheduling and spare parts inventory.
The NCLR500 offers a 200 kAIC interrupt rating, enabling rapid disconnection of severe faults with minimal energy release. This improves equipment protection, reduces arc energy, and supports system-level safety. For feeders and distribution circuits carrying up to 500 A, the high interrupt rating provides a margin against short-circuit events in demanding environments.
Yes. The Edison NCLR fuse is CE marked and UL listed, and CSA certified, meeting European and North American electrical protection standards. This certification set simplifies procurement for multi-region projects and supports compliance audits. When selecting fuses for critical equipment, maintaining these certifications ensures conformity with regulatory requirements and reduces risk during audits.
NCLR500 is ideal for industrial power distribution, switchgear, and motor control centers that require reliable, fast-acting protection for 500 A circuits. Its Class RK1, non-indicating design minimizes nuisance trips in some scenarios, while its 200 kAIC rating guards against high-energy faults. This makes it a practical choice for panels, MCCs, and light-to-heavy industrial loads.
Installers should note the fuse’s operating temperature range (-40°C to 85°C), voltage rating of 250 V, and glass-melamine tube construction for durability. Use standard mounting and fuse blocks compatible with RK1-class devices, ensure proper ventilation, and verify correct amperage rating. The product ships with standard packaging and requires no special tools beyond typical protective equipment.
