VC-V12 AC Metal-clad Switchgear Made in China - Suppliers and Manufacturers

Product Description

1.Product Introduction

The applicable standards for VC-V12 AC Metal-clad Switchgear are IEC298, GB3906, DL404 etc. And this switchgear is of the interlocking function of protecting from miss operation of opening and closing of the vacuum circuit breaker (VCB for short) protecting from withdrawing of loading VCB or loading withdrawable disconnect-link trolley. Protecting from closing of VCB when the earthing switch is closed, protecting from closing of earthing switch when the system is on load, and protecting from entering of the loading compartment, and it is distribution equipment with advanced performance and function.
