Power Solution Information

The APT Front Access Switchgear is a Compact Medium Voltage (2.4kV – 15kV) air insulated SF6-free Switchgear that utilizes state-of-the-art innovative switchgear design methods and technology. This allows for a smaller and lighter design that offers the peace of mind of visual assurance of full disconnection through the main bus connection window. This makes the FAC-Series the safest Medium Voltage Switchgear on the market. With each section’s small footprint (26″W x 38.5″D x 80″H), it will fit in places traditional sized switchgear cannot. It’s also easy to install on-site, reducing assembly time.
