Quick Connection Switchgear Information

The APT MF2-Series Generator/Loadbank Quick Connect Switchgear is designed to allow quick and safe connection of either a medium voltage mobile generator set or a low voltage mobile generator connected to a medium voltage step up transformer to facilities experiencing loss of power. The MF2-Series is ideal for facilities that require medium voltage (2.4kV to 15kV). The switchgear is rated Type 3R for outdoor installation. Permanent installation and connection of the switchgear to the facility power distribution system will minimize any unplanned power outages.
