More targeted protection of a power grid is the most important advantage of selective circuit breakers (SCB). However, there are other points to be considered: The SCB switch can be used as a central main switch. It offers the ability to reliably de-energise even a very large downstream distribution grid with numerous socket circuits and lighting circuits, all from a single point. This increases safety, not least in large and/or intricately laid-out areas and buildings. Although the SCB main switch ensures that the short-circuit current is reduced in the event of a short circuit, it does not completely switch off unaffected areas before its final actuation. This ensures their safe continued operation. It serves as a backup for the other installed circuit breakers and RCD switches or fuses. It offers lockability and sealability as standard. Hager SCB switches can also be equipped with a restart interlock. https://elecena.pl/product/23470921/hts116e-scb-switch-1p-e-16a-busbar-qc 2023-05-16 https://elecena.pl/product/23470921/hts116e-scb-switch-1p-e-16a-busbar-qc 2025-12-30 https://elecena.pl/product/23470921/hts116e-scb-switch-1p-e-16a-busbar-qc 2026-01-26 https://elecena.pl/product/23470921/hts116e-scb-switch-1p-e-16a-busbar-qc 2026-02-27
