Rittal Ri4Power Horizontal Busbar System 1600A

The Rittal Ri4Power Horizontal Busbar System 1600A (model 9340.285) is an engineered power distribution busbar system designed specifically for integration with Rittal's VX25 and TS8 baying enclosure systems to form complete, type-tested low-voltage switchgear and controlgear assemblies (LVCA) compliant with IEC 61439-1 and IEC 61439-2. The 9340.285 supplies 1600 A of continuous three-phase power distribution through a pre-engineered copper busbar assembly that mounts horizontally across multiple baying enclosure sections, providing a standardised, factory-tested power distribution backbone for motor control centres, main distribution boards, and large process automation panel assemblies. At 1600 A, the Ri4Power system covers the majority of industrial MCC applications in Saudi Arabia's petrochemical, power generation, and water treatment sectors without requiring custom busbar fabrication.

The Ri4Power system's principal engineering advantage is its system approach to type-tested switchgear. Rather than requiring the panel builder to engineer and test a custom busbar configuration from raw copper bar stock — a process that adds months to a project and requires access to a test laboratory — the Ri4Power 9340.285 is supplied as a fully factory-designed and type-tested system. The enclosure configuration, busbar cross-section, phase spacing, and earthing arrangement are all pre-validated to IEC 61439-2 by Rittal's engineers at the Herborn test facility, allowing Saudi panel builders to issue a Declaration of Conformity for their completed LVCA against the Rittal type-test reports without performing their own testing. This is a massive advantage on ARAMCO and SABIC projects where the engineering standard requirements for MCC type-testing documentation are stringent and the cost of non-compliance (project delays, re-testing, third-party inspection fees) is substantial.

In Saudi Arabia's largest MCC installations — at ARAMCO's Wasit gas plant, SABIC's UNITED and SHARQ affiliates in Jubail, and SEC's bulk supply substations across the Kingdom — horizontal busbar systems at 1600 A form the power distribution spine of entire production facilities. The Ri4Power 9340.285 allows ARAMCO-qualified panel builders in Dammam, Jubail, and Riyadh to construct fully type-tested MCC assemblies that satisfy both IEC 61439-2 and ARAMCO SAES-P-100 requirements in a single, documented package. For Vision 2030 projects including NEOM's utility infrastructure and the Ras Al-Khair industrial city expansion, where both technical performance and project schedule are under intense scrutiny, the Ri4Power system's pre-engineered, factory-tested approach eliminates a major source of project risk.

Razz Middle East supplies Ri4Power busbar systems directly to panel builders and EPC contractors across Saudi Arabia, and provides technical documentation packages including Rittal type-test reports, system data sheets, and IEC 61439-2 LVCA declaration templates to facilitate customer panel compliance submissions. Our engineers are available to assist with current rating selection, short-circuit withstand calculation reviews, and enclosure layout optimisation for specific project requirements.
