: They offer better contact area, reduce panel clutter, and handle higher currents (e.g., matching a 63A main switch ).

: These are pre-insulated copper bars with "teeth" that slide into the terminals of multiple breakers simultaneously. shema soedinenija avtomatov

: Hand-made bridges using insulated wire. : They offer better contact area, reduce panel

: Pin-type (universal pole structure) and Fork-type (U-shaped for screw terminals). : They offer better contact area
