Keep relay terminals below 150C max continuous, 175C max for two hours, and 200C for 1 minute. 170 mm sq. conductor size recommended for 600A carry (2X 3/0 AWG, 350 kcmil). See derating curve for current vs.ambient temperature operating ambient to +125C allowed with current derating. (2) Maximum Load Interrupt at 1000Vdc = 100Adc (3) Stabilized reading. Contact resistance may exceed spec in the first 3 minutes of current carry. (4) 1ms rise time, 10ms pulse duration.
