The currents shown above are the continuous rated for both AC and DC.
Higher currents (as generated by pulse driven instruments) can be used with an ON to OFF
time ratio of 1:10 or less. The allowed peak currents are 10 times those specified above, with
an upper limit of 1000 A and a maximum applied time of 4 seconds. At least 1 minute should be
allowed between applications for cooling.
NOTE:
It is important to ensure there are adequate low resistance connections to the 5070 current terminals.
