Why Choose the ABB ZK178 16–70 mm Connecting Terminal?
The ABB ZK178 16–70 mm Connecting Terminal (2CPX064978R9999) is a dedicated electrical connecting terminal intended for compatible ABB low-voltage sub-distribution assemblies. Belonging to ABB's DESUJ Sub Distribution product group, the ZK178 provides a manufacturer-specified connection component for electrical distribution installations requiring a terminal with a designated conductor size range of 16–70 mm².
Designed for professional electrical distribution applications, the ABB ZK178 supports the connection of appropriately specified conductors within compatible electrical equipment. Reliable electrical connections are essential in distribution assemblies, where conductor sizing, terminal compatibility and correct installation practices contribute to the performance and safety of the completed system. The ZK178's stated 16–70 mm size designation helps installers identify the required terminal, although the precise conductor cross-sectional area and compatible conductor types should be confirmed against ABB's technical documentation.
Supplied under ABB order code 2CPX064978R9999, the ZK178 is identified as a single-piece connecting terminal, making it suitable for component procurement, maintenance and replacement projects where this exact model is specified. Its manufacturer-specific designation supports accurate selection for compatible ABB distribution equipment, helping electrical contractors, panel builders and maintenance engineers avoid substituting unsuitable connection components.

Understanding Connecting Terminal Selection and Conductor Compatibility
Electrical connecting terminals are used in distribution equipment to establish electrical connections between conductors and designated connection points. Selecting the correct terminal is essential because conductor dimensions, conductor construction, terminal geometry and installation requirements must be compatible. An incorrectly specified or improperly installed connection can result in excessive contact resistance, overheating or unreliable electrical performance.
The ABB ZK178 carries the manufacturer's 16–70 mm connecting terminal designation. Electrical conductor sizes are commonly expressed as cross-sectional areas in square millimetres (mm²), but the abbreviated product description alone should not be used to establish every permitted conductor size or construction. Before installation, confirm the terminal's specified conductor cross-sectional area range, suitability for solid, stranded or flexible conductors, and any restrictions relating to conductor material or ferrules.
The exact connection method is also important. The supplied ZK178 designation does not establish whether the terminal uses a screw-clamp, bolt-type or another connection mechanism. Likewise, its rated current, rated voltage, tightening torque, material and number of permissible conductors per terminal are not confirmed by the supplied specification. These details must be obtained from the applicable ABB technical documentation and matched to the electrical distribution assembly.
For professional installations, the ABB order code 2CPX064978R9999 should be checked against the original equipment schedule or approved assembly documentation. Correct conductor preparation, installation torque where applicable, and verification of the completed electrical connection are essential parts of safe electrical assembly work. Installation should be performed by suitably qualified personnel in accordance with the manufacturer's instructions and applicable electrical regulations.
