FAQs
The NCLR225 is a 1-piece Edison fuse (Catalog Number NCLR225) with standard packaging designed for Edison-style fuse holders. It measures 8.63 in long and 2.38 in in both width and height, and uses a glass-melamine tube. For installation, verify you are using compatible Edison-style holders or blocks and ensure operation within the -40° to 85°C range. The non-indicating design means status checks should be performed via system-level protection monitoring rather than a built-in visual indicator. Always confirm panel compatibility with UL Listed and CE Marked components for regulatory alignment.
NCLR225 provides a 225 A amperage rating, 250 V voltage rating, and a 200 kAIC interrupt rating. These specs translate to strong short-circuit protection for industrial control circuits and feeders, enabling rapid interruption of fault currents and minimizing damage to downstream equipment. The Class RK1 designation indicates a standard time-delay characteristic suitable for systems with motor inrush or transient faults. This combination supports reliable protection while keeping nuisance trips manageable in typical panel environments.
Yes, the NCLR225 is designed for industrial protection within panel boards and control circuits. Its 225 A rating and 200 kAIC interrupt capacity provide robust defense against short circuits, including motor feeder faults. The 250 V rating suits standard low-voltage industrial systems, and its Class RK1 designation supports common inrush and fault conditions without excessive nuisance tripping. The device also benefits from UL Listed, CSA Certified, and CE Marked compliance, simplifying integration into compliant manufacturing environments.
NCLR225 carries UL Listed, CSA Certified, and CE Marked certifications. These marks certify conformity to recognized safety and performance standards across North America and Europe, supporting regulatory compliance for panel builders and OEMs. UL Listed confirms safety under standardized tests, CSA Certified provides Canada-specific validation, and CE Marked demonstrates conformity with European directives. Together, they streamline supplier qualification, customer audits, and international deployment of Edison-series protection.
Consider that NCLR225 is a non-indicating fuse, which means you won’t have a built-in visual fault indication. Plan for system-level monitoring or periodic electrical testing to verify fault conditions. The fuse ships with standard packaging and quantity one, which can simplify stocking and replacements in Edison-style blocks. While the data sheet notes no warranty, the device’s high interrupt rating and robust operating range (-40° to 85°C) can reduce downtime and replacement frequency in reliable systems, contributing to favorable total cost of ownership when applied to appropriate protection schemes.
