ETI SSQ 240 load break switch 1-0-2, 2P 40A (2421425)

ETI SSQ 240 is a three-position load break switch designed for manual switching of electrical circuits in the 1-0-2 positions. It is used in distribution boards, incoming power assemblies, and other low-voltage installation points where it is necessary to safely transfer a supply line, disconnect a circuit, or change between two sources without additional switching devices. The three fixed positions make it possible to carry out clear and controlled switching between operating states of the circuit. The device is rated for a current of 40 A at an AC voltage of 400 V. Two poles provide simultaneous switching of two conductors, which is suitable for circuits that require coordinated disconnection or transfer of two lines. The switch operates at 50/60 Hz, so it can be used in electrical networks with the most common mains frequencies. Compliance with IEC 60947-3 confirms that the device belongs to the category of low-voltage switching, disconnection, and control equipment. The IP20 degree of protection indicates protection against finger contact with live parts and defines indoor installation inside electrical enclosures, switchboards, or other protected housings. The permissible conductor cross-section is up to 16 mm², which allows connection of conductors of the corresponding size range and supports integration into circuits with suitable cable dimensions. These characteristics make the model appropriate for manual transfer and isolation tasks in household, commercial, and technical installations. As part of the ETI SSQ 240 series, this load break switch combines a practical three-position operating principle with electrical ratings intended for low-voltage control applications. It is a suitable solution for installations where reliable manual circuit switching, defined terminal capacity, and standardized mounting conditions are required.
