Selection Notes
- Semiconductor fuses are chosen on I²t let-through against the device surge rating, not on continuous current alone.
- Termination: Blade end x blade end. Confirm the mating clip or busbar before ordering; ferrule and blade ends are not interchangeable.
Common Questions
What are the ratings of the Eaton Bussmann FWX-800A?
600 V / 800A RMS, with a 200 kAIC Vac 50 kAIC at 250 Vdc interrupting rating.
How much fault current can the FWX-800A interrupt?
200 kAIC Vac 50 kAIC at 250 Vdc. The available fault current at the installation point must not exceed this value.
How does the FWX-800A connect?
Blade end x blade end. Confirm the mating clip, holder or busbar before ordering — ferrule and blade ends are not interchangeable.
How should I select the FWX-800A for a circuit?
Match the voltage rating to the system voltage, keep the continuous current above the load current, and check that the interrupting rating exceeds the available fault current. In medium voltage work, select on the transformer or feeder fault level rather than the load current alone.
