Power-Style QED-2 Switchboards (UL Listed)

QED-2 low voltage switchboards from Schneider Electric are built to last with durable construction and flexible design. These free-standing structures can contain circuit breaker overcurrent protection up to 5000 A at a maximum voltage of 600 Vac. QED-2 is future ready with the options of having advanced metering, continuous thermal monitoring, ArcBlok, and communicating trip units. Pair QED-2 with EcoStruxure Power, Asset Advisor, or Energy Hub. QED-2 offers a wide variety of features and pre-engineered designs with optimized lead times. Custom versions of switchboards are also available to accommodate project specific design criteria. The QED-2 frame allows various special components to be mounted in the switchboard, saving time, money and space in the field. These components include automatic throwover systems, automatic transfer switches, and special metering systems. This flexibility means the QED-2 switchboard can meet customer requirements on the most complex applications.
