Chassis Vehicle Door Closing Interlock Device

The chassis door closing interlock device is installed on both sides of the traditional chassis rocking valve. When the cabinet door is open, the rocking handle cannot be inserted to rock the chassis. The rocking handle can only be inserted after the cabinet door is closed. This interlock function does not require changes to the cabinet door.

10kV, 24kV withdrawable high voltage vacuum circuit breaker.

Chassis Vehicle Door Closing Interlock Device has many advantages:

•  Compared with the traditional chassis vehicle door closing interlock module, it is more stable and reliable.
•  When the cabinet door is not closed, the handle cannot be forcibly inserted to operate the rocking operation.

Many applications :

• Installed on the chassis of 10kV and 24kV withdrawable high-voltage vacuum circuit breakers.
