* 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)
? Typical Melting I 2 t (Measured with a battery bank at rated DC voltage, 10x-rated current, but not exceeding the interrupting rating. Time constant of calibrated circuit less
than 50 microseconds). Test current not to exceed interrupting rating of 50A.
? 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.
