Selection Notes
Check the voltage rating against the system voltage, and the interrupting rating against the available fault current, before specifying.
Common Questions
What are the ratings of the Eaton Bussmann FWA-70B?
700 V / 70 A, with a 200 kAIC interrupting rating.
How much fault current can the FWA-70B interrupt?
200 kAIC. The available fault current at the installation point must not exceed this value.
How should I select the FWA-70B 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.
