Notes: 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. 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 Derating Curve”for additional derating information. Devices designed to be mounted with marking code facing up. 2. Nominal Resistance measured with < 10% rated current. 3. Nominal Melting I²t measured at 1msec. opening time. 4. Nominal Voltage Drop measured at rated current after temperature has stabilized. © 2018 Littelfuse, Inc.

Note: 1. Rerating depicted in this curve is in addition to the standard derating of 20% for continuous operation. Example: For continuous operation at 75 degrees celsius, the fuse should be derated as follows: - I = (0.80)(0.85)IRAT = (0.68)IRAT ## ~~**Average Time Current Curves**~~ **==> picture [243 x 317] intentionally omitted <==** **----- Start of picture text -----**
