4A0026.00-000 Power Cable

The 4A0026.00-000 is a dedicated industrial power cable developed for B&R automation systems, designed to provide stable power transmission between power supply units, control modules and on-site electrical equipment. Adopting high-grade conductive materials and reinforced insulation structure, this cable features excellent electrical conductivity, mechanical durability and environmental adaptability. It is engineered for both fixed laying and flexible routing scenarios in industrial control cabinets and production sites, supporting long-term continuous power supply. The integrated connector design ensures fast and reliable plug-and-play connection, reducing on-site wiring time and minimizing poor contact risks. With outstanding oil resistance, wear resistance and electromagnetic interference suppression performance, it can adapt to complex industrial environments and serve as a reliable power transmission medium for B&R modular automation platforms.

The official model of the product is 4A0026.00-000, an original B&R product manufactured in Austria and compliant with the brand’s global quality standards and international industrial cable specifications. This cable is produced according to IEC and EN industrial electrical standards, and has obtained CE and UL certifications to meet international electrical safety and electromagnetic compatibility requirements. It is a standard-length power cable with integrated industrial-grade connectors at both ends, enabling direct connection with matching B&R power modules, CPU bases and I/O modules without additional wiring processing. The overall structure follows industrial cable design norms, with a compact outer diameter and neat wire arrangement, facilitating wiring and arrangement inside control cabinets. Each cable undergoes strict continuity test, insulation resistance test and connector tensile test before leaving the factory to ensure consistent quality and reliable connection performance. It is a dedicated accessory for B&R automation systems and can be widely matched with mainstream modules of the brand’s multiple series.

The core function of the 4A0026.00-000 power cable is to transmit rated power for B&R industrial automation equipment, acting as the key power transmission link between the system power supply and various functional modules. It undertakes the task of distributing stable voltage and current to CPU modules, I/O modules, communication modules and other units, ensuring the normal start-up and continuous operation of the entire control system. The built-in multi-core conductors achieve independent transmission of power lines and ground lines, with reasonable wire layout to avoid internal signal interference.

This cable supports two application modes: fixed installation and flexible wiring. In fixed scenarios such as internal wiring of control cabinets, it can be laid along cable grooves and fixed with accessories to maintain a tidy wiring layout. In scenarios requiring frequent movement such as cable drag chains and movable equipment parts, its excellent flexibility and bending resistance can withstand repeated bending and dragging. The standardized connectors at both ends feature foolproof design and locking structure, which can effectively prevent loosening caused by vibration during equipment operation and ensure the stability of power connection. In the overall system architecture, it can be used for single-unit module power supply connection, and can also be used for power expansion and cascade connection between multiple racks and multiple modules. As a supporting accessory for B&R automation solutions, it simplifies system wiring, improves construction efficiency, and guarantees the stable power supply foundation for the normal operation of the automation system.

The 4A0026.00-000 adopts stranded tinned copper conductors, which have low resistivity, good conductivity and oxidation resistance, ensuring low power loss during long-distance power transmission. The cable insulation and outer sheath are made of high-performance polymer materials, with a rated voltage of 300/500 V, and can withstand the voltage fluctuation of conventional industrial power grids. The insulation layer has high dielectric strength, with a withstand voltage of 2000 V for 1 minute, effectively preventing electric leakage and electrical breakdown.

In terms of mechanical properties, the cable has good flexibility. The minimum bending radius is 5 times the outer diameter for fixed installation and 10 times the outer diameter for flexible moving applications. It has excellent wear resistance, oil resistance and chemical corrosion resistance, and can resist the erosion of industrial oil, grease and common chemical agents on site.

For environmental adaptability, the rated operating temperature ranges from -25°C to +70°C, and it can withstand short-term temperature changes in industrial environments. It supports normal operation under relative humidity of 5% to 95% non-condensing conditions, and has certain anti-aging and anti-ultraviolet capabilities. The cable structure is designed to suppress electromagnetic interference, which can reduce the impact of external electromagnetic signals on power transmission and avoid affecting the normal operation of surrounding signal cables. The integrated connectors have good vibration resistance and tensile resistance, and can maintain stable connection under long-term mechanical vibration conditions.

The 4A0026.00-000 is pre-assembled with standard connectors that are fully compatible with the power interfaces of B&R 2005 series, X20 series and other mainstream modules, and can be directly plugged and used. For on-site fixed laying, standard cable clips, cable grooves and wiring fixing accessories are required to organize and fix the cable, which need to be selected according to the actual wiring path and cabinet layout. When used in cable drag chains, special drag chain accessories and cable protection sleeves are recommended to reduce wear caused by repeated movement and prolong the service life of the cable.

For multi-module and multi-rack system expansion, it can be used in combination with B&R dedicated bus extension cables and power distribution terminals to realize unified power supply for the whole system. Professional cable management tools and marking labels can be equipped to mark the cable number and power direction, which facilitates daily inspection, maintenance and fault troubleshooting. For scenarios with high electromagnetic compatibility requirements, external shielding accessories and grounding components can be configured to further enhance the anti-interference performance of the power circuit. All matching accessories comply with B&R unified specifications, featuring high compatibility and easy selection and replacement.

The 4A0026.00-000 power cable is specially matched with B&R industrial automation products, and is widely used in automation control systems built on B&R modular platforms. It is mainly applied to general machinery manufacturing, automated assembly lines, packaging machinery, textile machinery, food processing equipment, printing machinery, material handling equipment and intelligent testing equipment.

Thanks to its reliable power transmission performance and flexible wiring capability, it is suitable for both small independent single-device control systems and large distributed multi-rack control systems. It can work stably in production workshops with vibration, oil pollution, humidity and electromagnetic interference, and meets the power supply requirements of continuous operation of industrial equipment. It is applicable to both new automation project construction and technical transformation, wiring optimization and equipment upgrading of old production lines. Whether it is internal wiring of standard control cabinets or power connection of on-site movable equipment, this cable can provide stable and safe power transmission support. It is a universal and cost-effective power accessory for B&R automation systems.

The 4A0026.00-000 is an original genuine product of B&R Industrial Automation. All production processes including conductor stranding, insulation extrusion, sheath processing, connector assembly and finished product testing are carried out in strict accordance with international industrial cable standards and the company’s strict internal quality control system.
