2CDL701001R0250 ABB UNICLIC 250A 36-24 System pro E Energy 250A 24-Module 3P+2N Busbar Distribution Block

Why Choose the ABB UNICLIC 250A 36-24 Busbar Distribution System?

The ABB UNICLIC 250A 36-24 is a 250 A, 24-module plug-in busbar distribution block designed for efficient electrical power distribution within low-voltage switchboards and distribution assemblies. Part of the ABB System pro E energy range, this Uniclic system provides an organised distribution arrangement for connecting compatible modular electrical equipment, including miniature circuit breakers and associated distribution devices.

Featuring a three-phase and neutral distribution arrangement, the UNICLIC 250A 36-24 is identified in ABB's catalogue as a 3P+2N, 24-module distribution block. It combines uncoated copper connection elements with a grey PC+PU resin body and a transparent PVC protective profile. The system has a 400 V nominal voltage, 250 A nominal current and IP20 protection rating, supporting structured electrical distribution within suitable protective enclosures.

With catalogue dimensions of 422 × 40 × 50 mm (length × width × height), the UNICLIC 250A 36-24 provides a compact distribution solution for its rated capacity. Its plug-in connection concept supports the use of compatible ABB Uniclic connectors and connection leads, helping electrical installers create organised outgoing circuit arrangements while reducing the need for individually fabricated distribution connections.

Efficient Plug-In Power Distribution for Electrical Switchboards

The ABB Uniclic distribution system provides a structured method of distributing electrical power to compatible modular devices within low-voltage switchboards. Rather than relying solely on individual wiring connections between distribution points, the system uses a common busbar arrangement and compatible plug-in connection accessories. This approach can simplify circuit organisation and support consistent connection layouts within suitable electrical distribution assemblies.

The UNICLIC 250A 36-24 is designed for 250 A nominal current and incorporates a 24-module distribution arrangement. Its copper connection elements provide the conductive paths, while the insulating resin body and protective profile support the IP20 protection design. The specified 10 kA short-time withstand current for 1 second and 61 kA peak withstand current are important considerations when assessing the suitability of the distribution block for an installation's prospective fault conditions.

When integrating the Uniclic system into an electrical distribution assembly, installers must select compatible connection accessories and verify conductor ratings, upstream protection, operating voltage, thermal conditions and short-circuit coordination. The distribution block does not independently provide overload, short-circuit or residual current protection. Appropriate protective devices and a suitable enclosure must be incorporated into the completed installation in accordance with the manufacturer's instructions and applicable electrical standards.
