EATON Load break switch Main Construction
The load break switch is a 3-position switch, with Close, Open and earthing position. When in Open position, the moving blade has sufficient insulation distance. An operating handle can be used to make close-open operations on load break switch and earthing switch. There are mechanical interlocks between the load break switch and the earthing switch.
• The load break switch applies metal deionizing arc suppress technology, ensuring good interruption performance for the switch;
• The working speed of switch’s moving contact depends on its operation mecha nism; and the open-close speed of the switch will not be influenced by operators;
• When moving from closing to opening, the load break switch depends on moving contact speed and arc suppress devices simultaneously, to suppress arc and break current;
• The spring operation mechanism with an operating handle to complete closing and opening operations. Motorization module and opening coil can be added, to achieve remote control.
