Eaton NCLR4 Fuse - Class RK1, 200 kAIC UL Listed
Part Number: NCLR4
Quick Summary
Eaton Edison NCLR fuse provides fast overcurrent protection for control panels and industrial drives. In dense panel layouts, nuisance tripping and hard-to-trace faults drive downtime and maintenance costs. UL Listed, CSA Certified, and CE Marked, it helps regulators and operators meet safety and compliance requirements across multiple markets. Operating from -40° to 85°C in a compact 2 in length and 0.56 in width, it drops into standard fuse clips with minimal wiring changes. With a 4 A rating and 200 kAIC interrupt capability, it minimizes outages, while the standard 10-piece packaging reduces stocking complexity and expedites field replacements in automation environments.

Feature: 4 A amperage rating provides precise protection for low-current control circuits. Business Impact: reduces nuisance trips and extends the life of relays and control devices in fast-moving automation lines. Application: ideal for panel-mounted logic circuits, sensors, and signal lines in industrial machines. Feature: 200 kAIC interrupt rating offers robust short-circuit protection for feeders and branch circuits. Business Impact: improves system availability by tolerating large fault currents without catastrophic fuse blowout. Application: suitable for safely protecting consumer loads in machine assemblies and motor-control centers. Feature: 250 V voltage rating aligns with common control panel and automation electronics. Business Impact: ensures compatibility across typical 120/230 V service setups while meeting standard industrial codes. Application: used in low-voltage AC control circuits and power distribution within panels. Feature: Class RK1 and non-indicating design provides reliable, fast-acting protection with a simple status approach. Business Impact: supports quick fault isolation; no indicator means fewer false alarms in clean environments. Application: preferred in class RK1 tolerant circuits and standard Edison Bussmann fuse holders. Feature: Glass melamine tube construction delivers clear fuse link visibility and robust mechanical performance. Business Impact: ease of inspection and high-temperature resilience in cabinet environments. Application: suitable for standard fuse deployments in distributors and panel builders. Feature: -40° to 85°C operating temperature and standard packaging of 10 pieces. Business Impact: ensures reliable performance in harsh environments and simplifies stocking and replenishment. Application: ideal for field replacements and maintenance routines in manufacturing facilities.

FAQs
NCLR4 is designed for Edison Bussmann fuse holders with standard 2 inch length and 0.56 inch width. It fits typical control panel clip systems and mounting rails used in industrial automation, enabling quick swaps during routine maintenance without rewiring. The 10-piece packaging also supports stocking strategies and reduces downtime during replacements.
The fuse provides 4 A current rating, 200 kAIC interrupt capacity, and a 250 V rating. This combination protects sensitive control circuits from nuisance trips while offering robust short-circuit protection for feeders. Such ratings support selective coordination in panels and prevent collateral damage in adjacent circuits during faults.
Yes. With Class RK1 fast-acting characteristics and a wide operating temperature range, the NCLR4 is well-suited for control logic, sensors, and safety interlocks in automated processes. Its compact form factor and UL/CSA/CE certifications help ensure reliable protection without compromising panel space or compliance across facilities.
NCLR4 is UL Listed, CSA Certified, and CE Marked, signaling compliance with North American and European safety standards. These certifications reassure regulators, integrators, and end users that the fuse meets essential performance and reliability requirements for electrical protection in industrial settings.
The 4 A protection, high interrupt capacity, and standardized packaging reduce spare parts inventory and simplify stocking. The fuse’s long operating range and robust construction minimize unexpected failures, lowering maintenance labor costs and downtime while improving overall equipment effectiveness (OEE) in production environments.
