Circuit protection is a more technical application for terminal blocks. Terminal blocks can be equipped with fuses, circuit breakers, and other surge protection devices. These types of terminal blocks are commonly used in explosive areas and help protect against any form of overcurrent surge that may occur within the circuit. Terminal blocks can also be equipped with circuit breakers, which provide optimum protection against overload conditions for inductive loads. A built-in switching function enables immediate reset of the circuit and minimizes downtime for the system.
