Changeover Switches are used to switch the electrical power supply from EB (Electricity Board) to Power Generators and/or Solar Power supplies.
There are Manual and Automatic changeovers, where Manual changeover has a lever to change the power supply manualy. But automatic changeover is change the supply automatically when an interruption occurs by EB.
Automatic Changeover Switch
An automatic changeover is an electrical switch that switches a load between two sources. When EB/utility/Main power is lost, the automatic changeover sense the situation and switch to the generator, which starts to supply the power to the circuit.
Once the EB/Utitlity/Main power restored, it detects and returns to the main power.
Manual Changeover Switch
The Manual changeover switch requires to handle manually, when need a power switching from Main power to generator power or vise versa.
Rotary Type Changeover
There are Single phase and Three phase Rotary changeovers. These types can fix on the face of a Electric panel board. 1,0,2 (or ON/OFF/ON) positions are denoted to EB, Off, Generator.
MCB Type Changeover
These type changeovers can be fixed in a Main Distribution box (or in a ABC box). Also available single phase and 3 phase power installations.
These are commenly used in EB to Solar power supply circuit systems.
