Circuit Breaker Handcart has perfect and reliable interlock function. When it combines with mid-located unit and coordinate with EK6 switch, it can meet the requirements of Five-Pretecting Interlocker in GB 3906 standard, the detail effect of handcart interlock as follow:

 

1.In closing state, when handcart in working or isolated position, and with handle operating, the handcart won’t move, so that to prevent to pull handcart on- load.

 

2 .When handcart in working position, EK6 earthing switch can’t close, to avoid closing earthing switch.

 

3 .When handcart back to isolated state, after EK6 closing, the handcart can’t be moved to working position to prevent closing with earthing wire.

 

4.Once handcart is away from isolated position, when push the handart with handle to working position, during the way, can’t carry on closing operation.While after reached to working position, closing operation can be made.

 

5.There are 2 auxiliary switches (code S8,S9) installed on handcart, contact’s rated current is 15A . S8 gets 5 pairs NC contact,to make signal of isolated position.When handcart is in isolated position, auxiliary switch S8 is in closing state, while in working position,S8 is in open state. S9 gets 5 pairs NO contact to make signal of working position.When handcart is in isolated position,S9 is in open state,while in working position,S9 is close state.

 

6.After handcart getting into cabinet, as long as handcart is not in isolated position, it can’t draw out from the cabinet
