The WDK 2.5/TR-DU/O TNHE is a terminal block designed for wire sizes up to 2.5 mm², typically used for electrical connections in industrial and grounding applications. The "TR-DU" designation indicates that it is designed for mounting on DIN rails. The "O" might refer to a specific variant or feature of the terminal block, while "TNHE" typically refers to a type of earthing or grounding configuration, such as a "TN" system (Terra Neutral) for electrical installations. This terminal block ensures reliable and secure connections, particularly for earthing and grounding in systems that require compliance with specific safety standards.
