Product Q&A
Q:What is the main difference between VS1 and ZN63A-12?
A:
VS1 is the primary commercial model designation, while ZN63A-12 is the official Chinese national standard (GB) model designation for the exact same 12kV indoor vacuum circuit breaker.
Q:What phase distances (pole distances) are available for this VCB?
A:
Standard phase distances are 210mm and 275mm. The appropriate phase distance depends on the dimensions and internal clearances of your switchgear panel.
Q:Can this vacuum circuit breaker be supplied with both fixed and withdrawable (drawout) mounting?
A:
Yes. It can be supplied as a fixed installation unit or mounted on a handcart chassis for drawout applications in KYN28A-12 switchgear.
Q:What control voltages are supported for the operating mechanism?
A:
Standard control and secondary circuit operating voltages include AC 220V, DC 220V, and DC 110V.
