ETI SV 140 load break switch 1P 40A (2423123)

The ETI SV 140 load break switch is designed for switching electrical circuits under load in distribution boards and other electrical installations. It is used where a circuit must be manually connected or disconnected without interrupting the overall logic of the electrical system, providing clear local control of power supply to a single circuit. Such devices are commonly applied in residential, commercial, and industrial installations where routine isolation of equipment or individual lines is required. This model has 1 pole, so it is intended for control of a single phase line. The rated current is 40 A, which makes the device suitable for circuits with corresponding load levels. With this rating, the load break switch can be integrated into supply schemes for separate consumer groups and into assemblies where manual disconnection under operating current is needed. Its single-pole configuration also simplifies use in compact modular arrangements, especially in distribution panels where space and functional clarity are important. Unlike protective switching devices, a load break switch is focused on operational switching rather than automatic disconnection during fault conditions. Its main role is to provide controlled opening and closing of the circuit under load, which is particularly important during maintenance of panel equipment, redistribution of loads, or local isolation of a specific line. This makes the SV 140 a practical component in electrical systems that require manual control of power flow. The ETI SV 140 fits standard electrical installation scenarios where a straightforward switching device with a 40 A rating is needed. It is suitable for use as part of a structured distribution system, helping organize safe and convenient circuit isolation within the electrical network. The combination of 1-pole design and rated current of 40 A defines its application in single-line control tasks, where reliable manual switching is the primary requirement.
