Common Questions
What are the ratings of the Eaton Bussmann FWH-90BC?
500 V / 90 A, with a 200 kAIC at 1000 Vac 50 kAIC at 500 Vdc interrupting rating.
How much fault current can the FWH-90BC interrupt?
200 kAIC at 1000 Vac 50 kAIC at 500 Vdc. The available fault current at the installation point must not exceed this value.
How does the FWH-90BC 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-90BC 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.
