Information About JJN-90
The JJN-90 is a high-speed fuse from Eaton’s Bussmann Series developed to protect power electronics and distribution systems from severe overcurrent events. It is manufactured as a Class T fuse, enabling extremely fast fault interruption and current limitation in compact form factors. The fuse is designed for systems operating up to 300 volts AC and 160 volts DC, supporting both industrial AC power and DC applications. Its construction and electrical characteristics make it suitable for installations where equipment protection, fault containment, and system reliability are critical.
Key Features
- Class T Fuse Design: Provides very fast current-limiting performance to protect downstream equipment from high fault currents.
- High Interrupting Capacity: Rated at 200 kA at 300 V AC and 20 kA at 160 V DC for demanding fault conditions.
- Very Fast Acting Response: Minimizes let-through energy to reduce thermal and mechanical stress on protected components.
- Bolt-On Blade Connections: Ensures secure mechanical mounting and low-resistance electrical contact.
- Dual AC and DC Ratings: Suitable for use in both alternating and direct current systems.
- Non-Indicating Construction: Designed for standard protection applications without visual fuse status indication.
- VFD Line Protection Capability: Commonly applied in variable frequency drive circuits to safeguard sensitive electronics.
The JJN-90 delivers the reliability and precision required for high-speed overcurrent protection in critical power distribution and motor drive applications.
