* AC Interrupting Rating (Measured at rated voltage with a unity power factor); DC Interrupting Rating (Measured at rated voltage, time constant of less than 50
microseconds, battery source)
** DC Cold Resistance (Measured at 10% of rated current)
† Typical Melting I2t (Measured with a battery bank at rated DC voltage, 10x-rated current, not to exceed IR, time constant of calibrated circuit less than 50
microseconds) (6.5A & 7A measured at interrupting rating)
‡ Typical Voltage Drop (Measured at rated current after temperature stabilizes)
It is recommended that fuses be mounted with ceramic (white) side facing up.
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.
