The ETI SV 4100 load switch is intended for switching electrical circuits under load in distribution boards, incoming feeders, and group lines. It is used where manual connection or disconnection of power is required without the automatic protection function. Such equipment is suitable for industrial, commercial, and residential electrical networks, especially when safe circuit isolation is needed during maintenance, inspection, or operating mode changes. This model is supplied in a 4-pole version, which makes it possible to switch three phase conductors and the neutral conductor at the same time. This is particularly important in three-phase systems where full disconnection of the supply circuit is required. The 4-pole design helps ensure complete separation of the line from the power source and is often used in main incoming circuits and other power sections of electrical installations. The rated current of 100 A defines the device’s application in circuits with significant load. It is suitable for power feeders and distribution sections where a switch-disconnector with an appropriate current rating is needed. At the same time, it should be noted that a load switch is meant specifically for switching under load and does not provide protection against overload or short circuit. For this reason, it is installed together with protective devices that perform the protective function in the switchboard. SV 4100 belongs to the category of load breakers and disconnect switches, which reflects its role as a manual switching device for electrical circuits. In switchboard assemblies, such equipment is used to organize clear separation between switching and protection tasks, making circuit control more straightforward. With its 4-pole construction and 100 A rating, the device is appropriate for installations where reliable manual disconnection of a power line is required.
