SBU-Series 208V-480V UL891 Listed Switchboard

208V, 480V, 600V - Low Voltage Paralleling, Transfer, & Distribution Fully Assembled Electrical Switchboard Up to 4000A Main Bus

This complete line of 208V – 690V indoor and outdoor switchgear is the ultimate in flexibility and has options available to meet virtually any power system needs.

Switchboards can be custom designed or utilize a standard
configuration to meet specific dimensional and electrical
requirements. They can include fully integrated component options
from leading manufacturers, including automatic transfer switches,
SPD, distribution transformers, and PLC or relay based transfer
schemes, Automation, Metering and Monitoring. Circuit breakers
and fusible switches can be group or individually mounted. Indoor
and outdoor enclosures are available in a wide range of durable color
finishes

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.
