Product Description

Secondary socket interlock mechanism Between Circuit Breakers



1. When the grounding switch is turned on, the back door of the switchboard can not be closed because when the grounding switch is turned on, a block is lowered, usually 30 to 50 cm below the switchboard, and there is a small bump on the door of the switchboard.
If the door can not be closed, the load switch can not be closed.


2. One type is mechanical interlocking, usually with a latch at the back of the load switch. When the cabinet door is opened, the latch is loaded with a spring that blocks the closing mechanism from the inside. So that it can not be protected. Close the door, and when the latch is put in, it closes.


3. This is less used now. There is also a type of electronic interlock, is in the cabinet door box on the edge of a contact switch, which is the top of the cabinet door, the load switch inside the electromagnet can start, after the start of the suction blocking mechanism, this can close.
