## **Note:** 1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting Rating tested at rated voltage with time constant < 0.8 msec. 2. Nominal Resistance measured with < 10% rated current. 3. Nominal Melting I[2] t measured at 1 msec opening time. - Devices designed to carry rated current for 4 hours minimum. It is recommended that devices be operated continuously at no more than 80% rated current. See _Temperature Re-rating Curve_ for additional derating information. - Devices designed to be mounted with marking code facing up. 4. Nominal Voltage Drop measured at rated current after temperature has stabilized. ## ~~**Temperature Re-rating Curve**~~ **==> picture [243 x 200] intentionally omitted <==** **----- Start of picture text -----**

Note: - Re-rating depicted in this curve is in addition to the standard re-rating of 20% for continuous operation. Example: - For continuous operation at 75º C, the fuse should be rerated as follows: - I = (0.80)(0.85)IRAT = (0.68)IRAT **==> picture [261 x 303] intentionally omitted <==** **----- Start of picture text -----**
