Common Questions
What are the ratings of the Eaton Bussmann FWH-400A?
750 Vac, 750 Vdc / 400A RMS, with a 50 kAIC at 500 Vdc 200 kAIC at 1000 Vac interrupting rating.
How much fault current can the FWH-400A interrupt?
50 kAIC at 500 Vdc 200 kAIC at 1000 Vac. The available fault current at the installation point must not exceed this value.
How does the FWH-400A 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 FWH-400A 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.
