Find the right transfer switch
Choose the switching method that matches your backup power system, operating requirements and required level of source isolation.
Monitors the power supply and automatically changes to the backup source when abnormal conditions are detected.
Best for
Allows an operator to select the main or backup power source manually for a simple, cost-effective solution.
Best for
Uses an interlocking mechanism to prevent the main and backup sources from being connected at the same time.

Backup power applications
Explore common source changeover applications and select the product type that matches your power system.
A transfer switch for generator systems moves the connected load between utility power and a backup generator during an outage or maintenance.
Compact transfer switches provide controlled source selection inside low-voltage distribution panels for buildings and small facilities.
Industrial transfer switches support machinery and control systems requiring dependable source changeover and isolation.
Choose the switching method, rated current and pole configuration according to your power sources and application.
Transfer switch selection guide
Confirm the switching method, rated current, number of poles and power source configuration before selecting a transfer switch. These four factors determine whether the device matches your electrical system.
Select automatic operation for unattended backup systems, or manual operation when an operator will change the power source.
Choose a current rating that matches the circuit load and system design. Available options cover common ratings from 10A to 100A.
The required pole configuration depends on the phase arrangement and whether the neutral conductor also needs to be switched.
Confirm the voltage, phase and type of main and backup supplies before choosing the final transfer switch configuration.
Send us your system voltage, rated current, number of poles and required switching method. Our team will help you confirm a suitable model.
Get Product Selection Support →A transfer switch changes the connected electrical load between two power sources, such as utility power and a backup generator. It helps prevent the two sources from supplying the circuit simultaneously.
An automatic transfer switch monitors the power supply and changes sources automatically when required. A manual transfer switch requires an operator to move the switching mechanism.
The rated current should match the circuit load and electrical system design. Consider the continuous load, starting current and protective device coordination before selecting a 40A, 63A or 100A transfer switch.
A 2-pole model is commonly used in single-phase systems. A 4-pole transfer switch may be required in three-phase systems when the neutral conductor must also be switched. Final selection should follow the local wiring system and project requirements.
Yes. Transfer switches can be used to change between utility power and a generator or inverter, provided the voltage, frequency, phase configuration and rated current are compatible.
GA&DA supports OEM branding, customized packaging and bulk order coordination. Provide the required model, current rating, pole configuration, quantity and packaging requirements when requesting a quotation.
Sample availability depends on the selected model and specification. Contact GA&DA with your required current, poles and switching method to confirm the sample arrangement.
