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/23702733/htn335e-scb-switch-3p-e-35a-rail-mounting 2023-06-27 https://elecena.pl/product/23702733/htn335e-scb-switch-3p-e-35a-rail-mounting 2023-10-25 https://elecena.pl/product/23702733/htn335e-scb-switch-3p-e-35a-rail-mounting 2024-01-31 https://elecena.pl/product/23702733/htn335e-scb-switch-3p-e-35a-rail-mounting 2025-04-07 https://elecena.pl/product/23702733/htn335e-scb-switch-3p-e-35a-rail-mounting 2025-05-11 https://elecena.pl/product/23702733/htn335e-scb-switch-3p-e-35a-rail-mounting 2025-05-17 https://elecena.pl/product/23702733/htn335e-scb-switch-3p-e-35a-rail-mounting 2026-01-03
