*
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 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.
