Electrical appliances connected to a three-phase main supply can be affected when one or more phases are not present. For applications using single-phase loads, an Automatic Phase Changer can provide an automatic way of managing the available phases.
At SELFGUARD Automation and Controls, we manufacture the SELFGUARD Three Phase Automatic Phase Changer (APC). Our Automatic Phase Changer is designed for a three-phase main supply and single-phase loads such as lights, fans, single-phase ACs and single-phase motors.
What Is an Automatic Phase Changer?
A Three Phase Automatic Phase Changer is a unit designed to work with a three-phase main supply.
Our SELFGUARD Automatic Phase Changer gives the output on all three phases when either one phase or two phases are present.
The unit is installed with a three-phase main supply only and is applicable for three-phase main supply and single-phase load only.
How Does SELFGUARD Automatic Phase Changer Work?
The SELFGUARD Automatic Phase Changer is designed to provide output when one phase or two phases are present.
When any of the missing phases comes back, the unit automatically shifts the load to its original phase. This operation is carried out with the help of an inbuilt delay timer.
This is the automatic phase-changing function provided by our APC for suitable single-phase loads connected to a three-phase main supply.
Automatic Phase Changer for Single-Phase Loads
The SELFGUARD Automatic Phase Changer is specifically applicable to single-phase loads connected to a three-phase main supply.
The applications mentioned for our Automatic Phase Changer include:
- Lights
- Fans
- Single-phase AC
- Single-phase motors
- Other single-phase loads
For these applications, the SELFGUARD APC is designed to work with a three-phase main supply.
Automatic Return to the Original Phase
A key feature of the SELFGUARD Automatic Phase Changer is its automatic shifting of the load back to its original phase.
When a missing phase comes back, the unit automatically shifts the load to its original phase with an inbuilt delay timer.
This automatic operation is an important part of the SELFGUARD APC's functionality.
SELFGUARD Automatic Phase Changer Ratings
Our Automatic Phase Changer is available in multiple ratings, from 63 Amps to 200 Amps.
The available ratings are:
- 63 Amps
- 100 Amps
- 125 Amps
- 150 Amps
- 200 Amps
The selection of the Automatic Phase Changer is done according to the load of the mains.
The 63 Amp model has a size of 300 × 250 × 115 mm. The 100 Amp, 125 Amp, 150 Amp and 200 Amp models have a size of 375 × 310 × 135 mm.

Automatic Phase Changer for Three-Phase Main Supply
The SELFGUARD Automatic Phase Changer is designed specifically for a three-phase main supply and single-phase load.
This makes it applicable for single-phase loads such as lights, fans, single-phase ACs and single-phase motors.
The unit is installed with a three-phase main supply and provides output when either one phase or two phases are present. When a missing phase comes back, the unit shifts the load automatically to its original phase with its inbuilt delay timer.
Conclusion
The SELFGUARD Three Phase Automatic Phase Changer (APC) is designed for three-phase main supply and single-phase loads.
It gives output when either one phase or two phases are present and automatically shifts the load to its original phase when a missing phase comes back. The unit uses an inbuilt delay timer for this operation.
Available in ratings from 63 Amps to 200 Amps, the SELFGUARD Automatic Phase Changer can be used for suitable single-phase loads such as lights, fans, single-phase ACs and single-phase motors.
For selecting the appropriate Automatic Phase Changer, the selection is made according to the load of the mains.
