Common Questions
What are the ratings of the Eaton Bussmann RD40-3-508?
600 V / 40 A.
Which standards does the RD40-3-508 comply with?
It is referenced against UL 508 in the manufacturer data.
How should I select the RD40-3-508 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.
