2.4kV-38kV Metal Enclosed/Clad
Draw-Out Vacuum Circuit Breaker Switchgear

APT Medium Voltage (5kV – 15kV) metal enclosed distribution switchgear can be built for both indoor and outdoor installations. It is available in both full and compact sizes, and features vacuum circuit breakers. As a result, it offers the ultimate in flexibility with options available to meet virtually any power system needs. And with its minimum depth footprint (100"H x 36"W x 72"D), it will fit in places traditional sized switchgear can't.

2.4kV-15kV Metal Enclosed Compact Vacuum Circuit Breaker Switchgear

APT's MED-Series can meet requirements for most power distribution applications without bulky traditional sized switchgear. It can be built for both indoor and outdoor installations. In addition, APT Open or Closed Transition Automatic Transfer Modules are compatible with our MED-Series.


2.4kV-15kV Metal Enclosed Ultra Compact Switchgear
