NOTE: voltage rating of 350-400-450 A rated fuses is defined with a CC’ curve at 1 second limited by minimum breaking current.
• Voltage rating: 690 V with CC’ at 1s - 450 V with CC’ at 10 s
** Voltage rating: 600 V with CC’ at 1s - 450 V with CC’ at 10 s
Minimum operating voltage for trip indicator = 20 V
