Terminal block for horizontal series terminals 450x250 mm UD31A1

Universal block for distribution boards – a solid foundation for installation

This terminal block, with dimensions of 450x250 mm, is a basic element for building low-voltage distribution boards. Designed for horizontal mounting, it offers space for three DIN rails, allowing for flexible configuration and expansion of the installation. It is an ideal solution for both professional installers and end-users who value order and safety in the electrical system.

Construction and application

The block is made of high-quality plastic, which ensures its durability and resistance to mechanical damage. Designed for mounting series terminals or modular devices on a DIN rail, it allows you to create complete distribution boards up to 1600A at a voltage of 3AC 690V / 50Hz. The distance between rows of 150 mm provides convenient access to the elements and facilitates cable routing. The possibility of expansion allows you to adapt the block to changing needs and add additional circuits.

Functionality and safety

The block is equipped with sealable protective covers that prevent accidental contact with conductive elements. Reinforcement using gas injection technology increases the strength of the structure. It meets the requirements of DIN EN 61439-1/-2/-3 and VDE 0660 Teil 600-1/-2/-3 standards, which guarantees compliance with applicable regulations and a high level of safety. This ensures that the installation is carried out correctly and meets all safety standards. In addition, the dimensions of the block (450 mm high, 250 mm wide and 125 mm deep) allow it to be easily adapted to different spaces and distribution board configurations.
