JJN-200 - 200Amp Fuse

JJN-200 - 200Amp Fuse

When you’re protecting heavy‑duty electrical systems, you need a fuse that can clear serious faults fast—and the JJN‑200 delivers just that. Rated for 200 amps and designed for high‑capacity systems like variable frequency drives (VFDs), industrial motors and large distribution circuits, this Class T fuse brings high‑level current‑limiting performance where it counts. With an interrupting rating of 200 kAIC at 300 VAC and 20 kAIC at 160 VDC, it’s built to handle severe short‑circuit conditions without hesitation, giving your equipment the dependable protection it needs. The bolted blade end × bolted blade end connection ensures a secure fit and consistent contact—ideal when downtime isn’t an option.

Key Features and Benefits

• Fast‑acting current‑limiting technology: Clears fault currents quickly to protect downstream equipment, reducing damage risk and minimizing operational interruptions.
• Solid connection design: The bolted blade end design delivers stable electrical and mechanical interface, suited for high‑power installations where connection integrity matters.
• Non‑indicating style: A simpler design without an indicator window, making it a straightforward, high‑performance choice where monitoring the fuse element is not required.
• High interrupting capacity: With 200 kAIC at 300 VAC and 20 kAIC at 160 VDC, this fuse is built for systems that may face extreme fault energies—giving you peace of mind under heavy loads.
• Industrial‑grade protection: Ideal for demanding environments, it helps safeguard motors, drives and power distribution infrastructure against the unexpected.
