FAQs
The JJN-225 uses bolted blade end x bolted blade end connections, enabling secure mechanical attachment in switchgear and panelboards. Its compact 2.75 inch length, 1 inch width, and 1 inch height fit standard enclosures, simplifying retrofits. Use standard mounting hardware and ensure proper alignment with busbars for minimal resistance and reliable current path.
The JJN-225 is rated for 225 A with interrupt ratings of 200 kAIC at 300 Vac and 20 kAIC at 160 Vdc. It supports 300 Vac and 160 Vdc voltage ratings and comes in a standard package. It is a non-indicating Class T fuse, designed for high-energy protection in motor drives and control circuits.
Yes. The JJN-225 is a current-limiting Class T fuse with high interrupt ratings that limit fault energy in VFD line protection, preventing unnecessary tripping and reducing drive downtime. Its bolted blade ends and compact footprint facilitate quick integration into MCCs and control panels used for motor drives.
The JJN-225 is CE marked and RoHS compliant, aligning with European safety and environmental requirements. While the data sheet lists Class T as the fuse type, these regulatory markings help simplify approvals for global manufacturing and ensure compliance across multiple regions.
