Participation reward: 2 Wealth. Reward for the correct answer: 9 Wealth. High-voltage circuit breakers can not only cut off or close the ( ) and ( ) in high-voltage circuits, but also, when a fault occurs in the system, they cut off the ( ) and ( ) through the action of ( ).

High-voltage circuit breakers can not only cut off or close the (no-load current) and (load current) in high-voltage circuits, but also, in the event of a system failure, they can cut off the (overload current) and (short-circuit current) thanks to the action of (relay protection devices).
A high-voltage circuit breaker (also known as a high-voltage switch) can not only cut off or close the no-load current and load current in high-voltage circuits, but also, in the event of a system fault, it can cut off the overload current and short-circuit current thanks to the action of relay protection devices. It features a quite sophisticated arc-quenching mechanism as well as sufficient current-breaking capacity.
High-voltage circuit breakers can not only cut off or close the (no-load current) and (load current) in high-voltage circuits, but also, in the event of a system fault, they cut off the (load current) and (short-circuit current) thanks to the action of (relay protection devices).
