Transfer Switches

Reliable Source Switching for Critical Power

EEE manufactures both automatic transfer switches (ATS) and manual transfer switches (MTS) from 400A up to 5000A, listed to UL891 or UL1008, supporting telecom networks, data centers, utility infrastructure, hospitals and healthcare facilities, industrial facilities, and commercial businesses. Whether your application calls for automatic source transfer during an outage or manually controlled switching, our transfer switches are engineered to move critical loads between sources reliably, every time. Transfer switches can be supplied as standalone equipment or integrated directly into our switchboards or docking stations.

Automatic Transfer Switches

Our ATS design uses a breaker pair to transfer loads between sources, built three-pole only with a solid neutral — we don't offer switched neutrals on our ATS products. The controller and motor operators that drive the switch are manufactured in-house by EEE, giving us full control over the reliability and performance of the switching mechanism from end to end.

Manual Transfer Switches

Our MTS products offer more configuration flexibility, available in 3-pole or 4-pole configurations up to 480V, with either solid or switched neutrals depending on your application. Like our ATS line, MTS units use breaker pairs, paired with Kirk key interlocks to ensure safe, positive source selection.

Enclosure Options

Depending on amperage, transfer switches are available in free-standing or wall-mounted enclosures, available in Type 1, Type 3R, or Type 4X to match indoor, outdoor, or corrosive environment requirements.
