- 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-arcing I2 t are measured at 10In Current ** For 1A-5A, the color of glass coating is Green; for others, it’s Blue.Specifications are subject to change without notice. Application testing is strongly recommended.
