8PQ3212-0BA10 — Siemens SENTRON 8PQ Busbar Trunking System
The Siemens SENTRON 8PQ busbar trunking system (BTS) is a factory-assembled, type-tested power distribution system providing a flexible, modular alternative to multi-core cable for distributing large currents from main switchgear to load centres in commercial buildings, data centres, industrial facilities, and infrastructure projects. The 8PQ system covers rated currents from 100 A to 6300 A at up to 690 V AC with short-circuit withstand up to 80 kA, and its fully enclosed aluminium housing with IP55 protection rating surpasses the mechanical and environmental performance of cable trunking. Pre-fabricated straight sections, elbows, tees, and tap-off units in a 250 mm modular spacing grid allow power distribution layouts to be configured and reconfigured without specialist cable jointing skills.
The defining advantage of busbar trunking over cable distribution is the tap-off unit capability: standardised plug-in tap-off units at any 250 mm interval along the run accept circuit breakers, fuse switches, or switch-disconnectors to feed individual loads, and these tap-offs can be added or relocated while the busbar is energised in many configurations — providing the infrastructure flexibility demanded by data centres, factory floors, and commercial buildings where load layouts change frequently. The 8PQ's factory-assembled quality eliminates on-site cable-pulling variation, reduces installation time by 50–70% compared to multi-cable alternatives, and ensures consistent joint resistance throughout the distribution run.
In Saudi Arabia, the SENTRON 8PQ BTS KSA is gaining strong adoption in the Kingdom's data centre construction sector, where hyperscale facilities planned in Riyadh's Digital Mile and the NEOM tech district require the ability to reconfigure power distribution without infrastructure demolition. Commercial high-rise towers at King Abdullah Financial District and KAFD Phase 2 specify 8PQ busbar risers to carry 3200 A to 6300 A distribution from basement switchrooms to floor distribution boards — a duty that would require 6–8 parallel cable routes and complex cable management. Hospital main power distribution at new Ministry of Health facilities uses 8PQ systems for the main arteries serving critical care, theatres, and imaging suite distribution boards.
Razz Middle East designs and supplies complete 8PQ busbar trunking systems including layout optimisation, thermal rating verification for Saudi ambient conditions, and on-site installation supervision.

Key Features & Benefits
- Factory-assembled type-tested construction eliminates site jointing variability, providing consistent electrical resistance along the distribution run and guaranteed short-circuit withstand — advantages that site-assembled cable systems cannot replicate.
- Plug-in tap-off units at every 250 mm interval allow individual circuit breakers (up to 630 A) to be inserted at any point along the busbar run, with the ability to add or relocate tap-offs under live conditions to accommodate load changes.
- IP55 fully enclosed aluminium housing provides better mechanical protection than open cable trunking, withstands jet cleaning in food and beverage plant environments, and eliminates the fire propagation risk of exposed cable bundles.
- Rated current from 100 A to 6300 A in a common modular system allows a single product family to serve small commercial sub-distribution risers up to the main power spines of the Kingdom's largest hyperscale data centres.
- Aluminium conductor option reduces busbar system weight by up to 40% compared to copper equivalents, simplifying structural support design in high-rise buildings and reducing the load on suspended ceiling systems in data centres.
- 250 mm modular grid of tap-off positions provides the flexibility required by data centre operators to respond to tenant power demand changes without infrastructure replacement — a key Total Cost of Ownership benefit.
- IEC 61439-6 type testing at accredited laboratories provides the certified short-circuit withstand and temperature-rise data required for Saudi project specification compliance and SEC switchgear approval documentation.
Industrial Applications in Saudi Arabia
- Data centre main power distribution spines at hyperscale and colocation facilities in Riyadh's Digital Mile and NEOM tech district, where 3200–6300 A busbar risers distribute UPS output to server floor PDUs with tap-off flexibility for evolving rack layouts.
- Commercial high-rise building power distribution risers at King Abdullah Financial District and Jeddah Central towers, where 1600–3200 A 8PQ systems carry power from basement MSBs to floor distribution boards more efficiently than parallel cable routes.
- Hospital main power distribution arteries at new Ministry of Health facilities across Saudi Arabia, where the IP55 sealed system provides the hygiene and mechanical robustness required in clinical environments near sterilisation and theatre areas.
- Industrial manufacturing floor power distribution at SABIC and IKTVA plastics and chemicals plants, where plug-in tap-offs allow machine layout changes to be accommodated without rewiring the distribution infrastructure.
- Airport terminal power distribution at King Khalid International Airport Riyadh and Dammam expansion projects, where large current distribution across long terminal buildings favours busbar over multi-cable alternatives.
- Petrochemical plant main substation LV distribution from switchgear to MCC rooms, where the 8PQ's 80 kA fault withstand rating matches the high prospective fault currents at generator-backed industrial substations.
- NEOM city infrastructure power distribution for Sindalah island and The Line modules, where the modular reconfigurability of the 8PQ BTS supports the phased construction and evolving load layout of mega-project development zones.
