Step-by-step explanation:
An air break switch and an isolator are two different electrical devices used in power systems.
An air break switch is a type of switch used to interrupt or isolate the flow of electric current in a circuit. It is designed to break and make the circuit under normal operating conditions. Air break switches are typically used in outdoor installations and are capable of interrupting large fault currents. They often have manual or motorized operating mechanisms.
On the other hand, an isolator, also known as a disconnect switch or isolating switch, is a device used to disconnect a portion of a circuit or an electrical device from the power source. It is primarily used for isolating electrical equipment for maintenance or repair purposes, ensuring that it cannot be accidentally energized. It is typically operated manually and provides visible isolation or separation between the circuit or equipment and the power source.
While both devices serve the purpose of interrupting the flow of electric current, the key difference lies in their application. Air break switches are utilized for regular switching operations and fault current interruption, while isolators are primarily employed for maintenance or repair purposes to provide an extra layer of safety by disconnecting equipment from the power supply.
