*AC Interrupting Rating (Measured at designated voltage, 100% power factor random closing); 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)
†T ypical Melting I2t (Measured with a battery bank at rated DC voltage,
‡T ypical Voltage Drop (Measured at rated current after temperature stabilizes) ‡‡ Marking Code - 3 rd (U = USA, T = Taiwan and S = China)
• 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.
