The latest generation Legrand Data Centre Track Busway technology addresses the operational pressures facing today’s high-density, AI-intensive computing environments and is being well received by data centre facilities around the world.
The Legrand Track Busway system, engineered for reliability, safety and long-term efficiency, introduces modular, monitored power distribution infrastructure that supports scalable, fault-resilient data centre operations. The advanced track busway system supports current ratings from 160 A to 800 A and integrates key safety and monitoring technologies while simplifying installation and maintenance.
Legrand’s latest solution offers data centre operators who face the growing energy demands of AI-generated content and high-throughput networking a streamlined, intelligent approach to delivering uninterrupted power within compact, dynamic rack environments.
Notable features of the Legrand Track Busway compared to conventional busway systems include the combination of premium safety features, rapid tool-free installation, integrated intelligent monitoring and cost efficiency.
A standout feature is the fully tool-free Tap-Off Box (TOB) installation method, which uses a patented auto-hook mechanism and follows a ‘mechanical first, electrical second’ principle. This reduces risk during live expansion and ensures consistent, operator-safe connectivity. The TOB system requires no rotational alignment. Users simply insert vertically and engage the safety latch, completing the installation in seconds.
Straight sections of the system feature a lightweight, flat form structure with IP40-rated protection, enabling efficient use of ceiling space above racks, while maintaining secure conductor isolation. A ‘finger-safe’ conductor gap of 7 mm and integrated spring shims further enhance safety and mechanical reliability. With ≥ 99,95% copper purity and ≥ 97,6 % IACS conductivity, the system maintains strong thermal and electrical performance over an extended service period.
For sustainability-conscious operators, Legrand’s new design has advantages over conventional systems. Important benefits include 30% recycled copper and 30% recycled aluminium content in key components. By optimising conductor geometry and housing design, the system also reduces material usage and installation overheads, contributing to long-term energy and cost savings when compared with other systems.
Integrated intelligence features include four-point thermal monitoring at critical contact points (end feeds, joints and TOBs), with hot-swappable metering modules on both end feeds and tap-off units. These modules provide continuous tracking of voltage, current, power factor and joint temperature, ensuring real-time visibility into load and system performance. Communication options include Modbus-RTU and SNMP (v1/v2c/v3), allowing seamless integration into DCIM and facility management platforms.
Thermal derating data is included for operation in ambient temperatures up to 60°C and the system conforms to IEC insulation clearance and creepage standards. Installation is supported by a modular hanging and support kit, allowing for free positioning of brackets and flexible deployment, even in space-constrained ceiling voids. Standard clearance requirements of 600 mm (horizontal) and 700 mm (vertical) ensure compatibility with common data centre layouts.
The Legrand Data Center Track Busway system is available in both monitored and non-monitored configurations, and includes MCCB-equipped end feeds for simplified field maintenance and enhanced circuit isolation. Tap-Off Boxes are offered in multiple output formats (up to 63 A) with options for angled front or bottom drop-cord connections. All units have consistent dimensions for modular integration and hot-swap metering enables live maintenance without service disruption.
The integration of standard advanced functionality into this system, including hot-swappable meters, multi-point temperature sensing and a compact, installation-friendly profile that eliminates the need for costly add-on features or complex customisation. This results in a lower total cost of ownership, while delivering high performance, reliability and low maintenance requirements.
