*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)
†Typical Melting I
2
t (Measured with a battery bank at 10x-rated current, not to exceed IR,
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.
