Selection of Low-Voltage Switchgear

When selecting low-voltage switchgear, users need to consider factors such as rated current, short-circuit capacity, protection class, and expandability. For example, for applications with high short-circuit capacity, circuit breakers with high breaking capacity should be selected; for humid or dusty environments, switchgear with a high protection class should be selected. Furthermore, modularly designed switchgear facilitates future expansion and maintenance, making it suitable for applications where requirements may change.
