Vertical low-voltage switchgear

There are various types of low-voltage distribution cabinets, and the configuration of their internal components varies depending on the type. Taking the power cabinet as an example, from top to bottom, it usually includes knife switches, current transformers, air switches, and air switches for each branch. If direct control of electrical load is required, components such as contactors, thermal relays, and branch current transformers will also be equipped under the branch circuit breaker. In addition, it also includes measuring and monitoring equipment such as ammeters, voltmeters, voltage conversion switches, and indicator lights.
