It is recommended that 1. DC Interrupting Rating tested at rated voltage with time constant < 0.8 msecs. devices be operated continuously at no more than 80% rated current. See Temperature 2. Nominal Resistance measured with < 10% rated current. Re-rating Curvefor additional re-rating information. 3. Nominal Melting It measured at 1 msec. opening time. Devices designed to be mounted with marking code facing up. 4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
