* DC Interrupting Rating (Measured at rated voltage, time constant of less than 50 microseconds, battery source)
* DC Cold Resistance are measured at <10% of rated current in ambient temperature of 25degrees
* Typical Pre-arching I2t are measured at 10In Current
** For 1A-5A, the color of glass coating is Green; for others, it’s Blue.
