Load break switch ETI SV 425 4P 25A (2423422)

The ETI SV series load break switch is designed for manual switching of electrical circuits under load. It is used in distribution boards, incoming distribution units, and power lines where circuits must be connected or disconnected safely during normal operation. This type of device is intended for switching tasks and should be selected when a clear load-disconnection function is required without the protective functions of a circuit breaker. Model SV 425 is a 4-pole device, which means it can switch four conductors simultaneously. This is important in multipole networks and installations where complete isolation of several lines is needed from a single operating point. The 4P configuration supports coordinated disconnection of the circuit, making the switch suitable for applications where all poles must be opened together. The rated current is 25A, so the device is intended for circuits with a corresponding load level. This value is a key selection parameter, as it defines the current range in which the switch can be used within the design limits of the electrical system. Proper matching of the rated current to the network load is essential for correct operation in low-voltage installations. As a load break switch, this unit is applied as a switching element for local or general disconnection of parts of the network, operational changeover, and equipment servicing. In panel-based systems it helps organize manual control of power supply to individual sections while maintaining a clear and straightforward switching function. The ETI brand and SV series identification are relevant for compatibility checks during project design and equipment selection. Overall, the ETI SV 425 4P 25A is a compact switching solution for electrical panels and distribution systems where manual load switching is required. Its main technical features are the SV series designation, 4 poles, and a 25A rated current, which together define its scope of use in low-voltage electrical installations.
