KYN550-12 AC Metal-Enclosed Switchgear

The KYN550-12 AC Metal-Enclosed Switchgear features a "Five-Prevention" interlocking function designed to prevent: withdrawing or inserting the circuit breaker truck under load; inadvertent opening or closing of the circuit breaker; closing the circuit breaker while the grounding switch is in the closed position; accidental entry into a live compartment; and inadvertent closing of the grounding switch while the equipment is energized.The indoor medium-voltage solid-sealed vacuum circuit breaker trolley, supplied by Tianhe Electric, is a superior-performance power distribution device. The compact design of the KYN550-12 saves customers a significant amount of space within their power distribution infrastructure.

Product Features

Compact Design, Smaller Footprint: Occupying 30% less volume than standard KYN28 central-cabinet switchgear, this unit is perfectly suited for small-scale distribution rooms. It requires minimal floor space, allowing for the installation of withdrawable equipment even in the most confined environments.

Withdrawable Design, Maintenance Without Power Interruption: Retaining the classic withdrawable trolley structure, this system enables maintenance without the need for a complete power shutdown. If a fault occurs in a specific circuit, the corresponding trolley can simply be withdrawn; the remaining circuits remain completely unaffected, eliminating the need to de-energize the entire system—a functionality identical to that of standard KYN28 switchgear.

"Five-Prevention" Interlocking, Safe and Reliable: Featuring a dedicated "Five-Prevention" interlocking protection mechanism, the system thoroughly prevents operational errors and ensures the safety of 10kV high-voltage operations—providing the exact same level of safety protection found in standard KYN28 switchgear.

High Cost-Effectiveness, Lower Costs: Priced 20% lower than standard KYN28 switchgear, this unit offers exceptional value. For small-scale applications, there is no need to incur the high expense of purchasing a full-sized KYN28 unit; the KYN550-12 AC Metal-Enclosed Switchgear is more than sufficient for the task, resulting in significant cost savings.
