A power transfer switch is needed if you want to switch from a primary power source to a secondary or tertiary power source. It is also employed in many electrical power distribution systems across the world. You can see transfer switches in areas where there are emergency power generators used as backup power for utility source.
These switches ensure that the transfer of power source from the primary to another or vice versa is safe, while keeping each source isolated from each other. They can be employed in separate enclosures for standalone purposes, or can be employed as an indispensable component in equipment including Motor Control Centers Panelboards, Pow-R-Line C Switchboards, and Magnum DS Switchgear.

As mentioned earlier, a power transfer switch is a crucial component of an emergency and standby power system. If the normal power source is lost, a transfer switch swiftly shifts the load circuit from the regular power source to the emergency power source. This allows the critical loads to continue running with little or no power outage.
When the regular power source is restored, the transfer switch will again transfer back the power source to the regular or primary power source. There are four types of operational modes in switches: manual transfer switches, automatic transfer switches, non-automatic transfer switches, and bypass/isolation transfer switches.
There are three categories into which the power switching operation of switches may be separated. These are the Open Transition, Closed Transition, and Closed Transition Soft Load. The Open Transition is the Break-before-Make operation, while the Closed Transition is the Make-before-Break operation. In the Closed Transition Soft Load, both sources are in parallel position, and can be as such indefinitely.
In every transfer switch, you will see three components. It has the Power switching device to move the load circuits to and from the power source. The Transfer Logic Controller is used to monitor the condition of the sources of the power, and provide the control signals to the power-shifting device. Supplying operational power to the controller and switching device is the function of the Control Power Source.
Besides the Residential sectors, the Agricultural, Construction, and Industrial sectors also benefit from these switches. With the Residential type of switches, the homeowners are guaranteed to have protection in case of loss of power during a utility power interruption, personal injury and generator damage, loss of computer data from prolonged interruption, property loss because of freezing, and accidental connection of a generator to a utility.
The Agriculture industry uses the Wall Mount transfer switch for specific industry standards of reliability, endurance, and performance. Also come in different operational modes, the transfer switches for agriculture are flexible and reliable. They also provide under-frequency and over-frequency protection of the generator and utility power source.
The Industrial sector can use the Wall Mount, Magnum Floor Mount or Magnum Bypass/Isolation power transfer switches, depending on their specific needs and purposes. But regardless of which industry is using them, the switches are a sure way of enjoying the benefits of electric power.
