- ** 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, 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.
