10 Technical data | VD4 Vacuum Circuit-breaker
Note: 1) For DC 24V, 30V, 48V, 60V, 110V, 125V, 220V, 240V; AC 110V, 220V, 240V
2) Spring in the diagram is discharged. Standard configurations and options available for VD4 are contained in the diagram. Also see relative catalogues and order
forms for all possible configuration.
3) Releases and blocking magnets are fundamentally wired with rectifiers (e.g. magnet holder 45 with integrated rectifiers V1, V2, V3 and V9). Rectifiers function as
free-wheeling diodes with DC supply.
