*AC Interrupting Rating (Measured at designated voltage, greater than 95% power factor); DC Interrupting Rating (Measured at designated voltage, time constant of the calibrated circuit is less than 1 millisecond, battery source)

**DC Cold Resistance (Measured at ≤10% of rated current)

†T ypical Melting I2t (Measured with a battery bank at 10x-rated current, not to exceed IR, time constant of calibrated circuit less than 50 microseconds)

‡ T ypical 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.
