Load break switch ETI SV 1125 1P 125A (2423117)

The ETI SV 1125 load break switch is designed for switching electrical circuits and for manual switching on and off of loads. It is used in distribution boards, power cabinets, and other electrical installations where circuit disconnection is required without the functions of automatic protection. Such equipment is suitable for service operations, sectioning, and local isolation of individual lines when manual control of supply is needed. This model has 1 pole, which determines its use in single-phase or single-conductor circuit sections depending on the connection scheme. The single-pole design is intended for applications where one circuit path must be opened or closed manually. A rated current of 125 A allows the device to operate in circuits with significant load within the declared parameters, making it suitable for input switching, line isolation, or branch disconnection in power distribution systems. As a load break switch, the SV 1125 performs a commutation function rather than a protective one. It is not designed to trip on overloads or short circuits; instead, it provides manual switching of the circuit and separation of the load from the supply line. This distinction is important when selecting equipment for switchboards, because the device must be used together with appropriate protection devices if overload and short-circuit protection is required. The ETI SV 1125 1P 125A can be applied in industrial, commercial, and residential electrical systems where reliable manual switching of power circuits is necessary. Its configuration with one pole and a 125 A rating makes it a practical solution for control and disconnection tasks in electrical distribution assemblies, where quick isolation of a circuit is needed for maintenance, operational changes, or equipment servicing.
