Acti9 screw distribution block 14 holes 250A 1P LGY125014

Professional distribution block for single-phase installations

The Linergy DS LGY125014 distribution block is a high-quality distribution component designed for professional single-phase (1P) electrical installations. The product belongs to the renowned Acti9 series by Schneider Electric and ensures reliable electrical power distribution in complex systems.

Design and technical parameters

The device features a robust design with a rated operational current of 250A, allowing it to handle even highly loaded single-phase circuits. The block is equipped with 14 connection terminals, enabling even power distribution to multiple loads.

The device dimensions are 85 mm height × 36 mm width × 50.5 mm depth, providing a compact form while maintaining high functionality. The product weight is just 163g, which facilitates installation and does not place excessive load on the structure.

The rated insulation voltage Ui = 500VAC and the rated impulse withstand voltage Uimp = 8kV guarantee safe operation in industrial and residential conditions. The device operates with voltages of 230VAC (Ph/N) and 440VAC (Ph/Ph), making it versatile for various types of installations.

Compliance and operating conditions

The product meets the strict requirements of international standards IEC/EN 60947-7-1 and IEC/EN 61439-1 and 2, confirming its high safety standards and manufacturing quality. The dielectric strength according to IEC/EN 60947-1 is 2500VAC.

The distribution block maintains full functionality across a wide operating temperature range from -25°C to +55°C, allowing for use in both heated and unheated rooms, as well as in high-temperature industrial environments.

The pollution degree is 3, and the overvoltage category is III, ensuring adequate protection against surges in typical building installations.

Practical advantages for the installer and end user

The device mounting is extremely versatile—it can be installed on a standard DIN rail or directly onto a mounting plate, providing flexibility in switchboard design. This feature significantly simplifies the installation process for both new projects and the modernization of existing systems.

The maximum conductor cross-section is 120 mm², allowing for the connection of thick power cables without the need for additional intermediate elements. At the same time, the device supports a wide range of wire cross-sections, from small auxiliary connections to the main power supply.

The white color (RAL 9003) ensures an aesthetic appearance in modern switchboards, and the absence of a sealing cover simplifies service access without the need to break a warranty seal during installation modifications.
