APT Medium Voltage (5kV – 15kV) Metal-Clad Switchgear can be built for both indoor and outdoor installations. It is available in both full and compact sizes. In addition, the 15A-Series features vacuum circuit breakers. A vacuum circuit breaker can be removed from switchgear for high performance. This Medium Voltage Metal-Clad Switchgear can use several master, transfer, and paralleling switchgear controls. As a result, it offers ultimate extra safety safeguards and flexibility with options available to meet virtually any power system needs.
The APT Metal-Clad Automatic Transfer Switchgear (ATS) is a medium voltage product used to switch power from a normal source to an emergency source. As a result, it uses various transfer switchgear control methods. A feature the 15A-AT can have is one side containing the control panel between two voltage transformers (two sources). Therefore, the other side can have two circuit breakers on top of each other (one from each electrical source).
