The Hager AC changeover switch is a device used to switch power supply between two sources, typically between the main power supply and a backup generator. The “AC” in its name stands for “Alternating Current,” which refers to the type of power it is designed to handle.
The “63A” rating indicates the maximum current capacity of the switch, which is 63 amperes. This means that the switch can handle a maximum current of 63 amps without being damaged.
The “2 pole” specification indicates that the switch has two poles or connections, which are used for switching the two sources of power. This type of switch is commonly used in residential and commercial applications where a backup power supply is required.
It’s important to note that installation and use of this switch should be done by a qualified electrician to ensure safe and proper operation.
