Notes:  
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.  
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.  
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 re-rating  
information.  
3. Nominal Melting I²t measured at 1 msec. opening time.  
Devices designed to be mounted with marking code facing up.
