Transfer Switches

Reliably transfer business-critical l​oads to emergency sources with our line of industry-leading automatic and non-automatic tr​ansfer switches.

Transfer switches are applicable in many environments, ranging from residential, agricultural and light commercial applications to the critical power needs of healthcare, financial and data center facilities.

Automatic Transfer Switches

An Automatic Transfer Switch (ATS) continuously monitors the primary power source and, upon detecting a failure or significant voltage drop, automatically switches the connected load to a standby generator or alternate power source — all without any human intervention.

Once utility power is restored, the ATS transfers the load back and signals the generator to shut down. ATS units are ideal for critical facilities like hospitals, data centers, and commercial buildings where even brief power interruptions are unacceptable.

Manual Transfer Switches

A Manual Transfer Switch (MTS) serves the same fundamental purpose as its automatic counterpart — safely transferring an electrical load between a utility source and a backup generator — but requires a person to physically operate the switch.

When an outage occurs, an operator must manually initiate the transfer, making MTS units better suited for applications where a brief delay in restoration is tolerable, such as residential standby systems, light commercial use, or facilities that already have personnel on-site around the clock. MTS units are generally simpler, more cost-effective, and easier to maintain than automatic alternatives.

Service Entrance Switches

A Service Entrance Rated (SER) Transfer Switch is a specialized transfer switch that is approved and listed to serve as the main disconnect for a building's electrical service. Unlike standard transfer switches that are installed downstream of a separate main breaker, an SER transfer switch combines the functionality of a main disconnect and a transfer switch into a single unit.

This simplifies installation, reduces equipment costs, and saves panel space. SER transfer switches are commonly used in residential and light commercial applications where a dedicated, code-compliant main disconnect is required by the utility or local jurisdiction.
