MCCB with high interrupting capacity for line protection
Its interrupting capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, and 11.9 kA at 690 V — these figures define the maximum fault current it can safely clear at each voltage level, critical for selectivity coordination in high-fault installations. The auxiliary trip accessory order code is 3VA9608-0BB25.
Rated continuous current holds at 160 A from 40 °C through 50 °C ambient, then derates to 155.6 A at 55 °C, 151.2 A at 60 °C, 146.8 A at 65 °C, and 142.4 A at 70 °C (–).
