Product Q&A
Q:What is the difference between "Armored" and "Metal-Enclosed" switchgear?
A:
"Metal-Enclosed" means the switchgear has a metal shell with grounded partitions. "Armored" (Metal-Clad) is a higher standard it means each main circuit component (busbar, breaker, cable) is in its own separate, grounded metal compartment. The KYN28 12 is armored, providing superior arc-fault containment and safety compared to standard metal-enclosed types.
Q:What is the meaning of "Withdrawable" and why is it important?
A:
"Withdrawable" means the vacuum circuit breaker (VCB) is mounted on a handcart that can be pulled out of the cabinet. This allows for quick replacement or maintenance without dismantling the entire switchgear. It dramatically reduces downtime; you can simply swap the handcart and restore power immediately.
Q:What voltage and current ratings are available for KYN28-12?
A:
Standard ratings: Rated Voltage 12kV (also available in 3.6kV, 7.2kV); Rated Current 630A to 4000A; Rated Short Circuit Breaking Current 20kA to 40kA. Custom configurations are available upon request.
Q:What type of circuit breaker is used in KYN28-12?
A:
It uses a vacuum circuit breaker (VCB), typically models VS1, ZN63A, or VD4. Vacuum interruption is maintenance-free, eco-friendly (no SF6 gas), and highly reliable for medium-voltage applications.
Q:Does KYN28-12 have "Five-Prevention" interlocks?
A:
Yes. It is equipped with mechanical and electrical "Five-Prevention" interlocks to prevent
