Power Supply | 29.07.2026
We are expanding our product portfolio with the CU25003T busbar series from MEAN WELL. These grounding busbars feature high electrical conductivity, excellent corrosion resistance, and outstanding structural stability, helping to ensure the safe operation of equipment and systems. Typical applications include factory equipment, building installations, commercial facilities, transportation, and energy systems. The busbars safely conduct fault currents to ground through grounding devices, reducing leakage currents and touch voltages while enhancing the safety of both users and equipment. The dual-row design is rated for a maximum current of 250 A.
To meet a wide range of installation requirements, the CU25003T series is available in several versions with 5 to 27 terminals. The busbars are also designed for easy screw mounting and low-maintenance operation. MEAN WELL uses tin-plated red copper as the conductor material, providing high electrical conductivity and reliable corrosion protection. The mounting base is made of 6410G5 PA66 flame-retardant plastic and complies with the UL 94 V-0 flammability standard. All versions of the CU25003T series are CE and RoHS compliant.
