*DC Interrupting Rating (Measured at designated voltage, time constant of less than 50 microseconds, batter y 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, time constant of calibrated
circuit less than 50 microseconds)
‡Typical Voltage Drop (Measured at rated current after temperature stabilizes)
• It is recommended that fuses be mounted with glass (blue) 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 fur ther derating required at elevated ambient temperatures.
