* ACInterrupting Rating (Measured at designated voltage, 100% power factor); DC Interrupting Rating (Measured at designated voltage, time constant of less than 50
microseconds, battery source)
** DC Cold Resistance (Measured at 10% of rated current)
† Typical Melting I2t(Measured with a batterybank at rated DC voltage,10x-rated current, time constant of calibrated circuit less than 50 microseconds)
‡ Typical Voltage Drop (Measured at rated current after temperature stabilizes)
Device designed to carry rated current for four hours minimum. An operating current of 80% or less of rated current is recommended, with further derating required at elevated
ambient temperatures.
