PASS-M0-24 — ABB PASS M0 Compact Secondary Substation
The ABB PASS M0 is a compact factory-assembled secondary substation that integrates a medium-voltage ring main unit (RMU), distribution transformer, and LV distribution board into a single self-contained outdoor unit on a common base frame. The complete substation arrives at site as a single factory-tested assembly requiring only MV cable connection, LV load cable connection, and commissioning — eliminating the separate civil works, structural steelwork, and on-site assembly of conventional transformer room substations. Typical on-site installation time for a PASS M0 is one to two days compared to four to eight weeks for a conventional built-up substation in a brick-built or concrete kiosk, providing a dramatic schedule advantage for fast-track infrastructure projects.
The PASS M0 accommodates distribution transformers from 250 kVA to 1000 kVA with primary voltage at 12 kV or 24 kV, feeding a 400 V LV distribution board with outgoing feeder circuit breakers for the LV network. The MV switching unit is an SF6 gas-insulated ring main unit with two cable-in/cable-out positions for ring main connectivity and one transformer feeder position — matching the standard SEC 13.8 kV ring main cable connection architecture used in Saudi Arabia's urban distribution networks. The GRP (glass-reinforced polyester) outer enclosure is rated IP44 for outdoor installation and has been designed to meet the visual aesthetics requirements for deployment in residential and commercial areas, with colour options to match urban streetscape requirements.
Saudi Arabia's rapid urban expansion under Vision 2030 — new residential cities, NEOM, Red Sea Project, ROSHN housing developments, and commercial mega-projects — requires the power distribution network to be deployed in parallel with urban construction, with substations needed at multiple locations simultaneously within tight project schedules. The PASS M0 addresses this challenge by factory-assembling the complete substation to SASO and IEC standards and delivering to site ready for connection, enabling the electrical infrastructure contractor to install ten or twenty substation units per month rather than the one or two per month achievable with conventional on-site construction. SEC's technical standards for public distribution substations accept factory-assembled compact substation designs meeting the required electrical specifications as alternatives to conventional kiosk substations.
Razz Middle East coordinates supply and delivery of ABB PASS M0 units for major project developers and electrical infrastructure contractors in Saudi Arabia, managing factory inspection, SEC technical approval documentation, and delivery logistics for projects requiring multiple simultaneous substation installations.

Key Features & Benefits
- Factory-assembled and factory-tested complete substation (MV RMU + transformer + LV board) arrives at site ready for cable connection, reducing on-site installation time from four to eight weeks for a conventional kiosk substation to one to two days — the critical schedule advantage for fast-track NEOM, ROSHN, and Red Sea Project civil works.
- SF6 gas-insulated ring main unit with two ring cable positions and one transformer feeder position matches the standard SEC 13.8 kV ring main architecture, enabling direct plug-and-play connection to the existing SEC ring main network without switchgear modification.
- SASO-certified and SEC technically approved compact substation design compliant with IEC 62271-202 provides the acceptance documentation required for SEC public distribution network connection approval — a prerequisite for connecting the substation to the SEC 13.8 kV ring main in all Saudi Arabia distribution zones.
- GRP enclosure with IP44 protection and UV-resistant surface treatment withstands Saudi Arabia's direct solar irradiation (up to 1000 W/m²), 50°C ambient temperatures, and desert sandstorm abrasion — maintaining enclosure integrity and transformer cooling air circulation over the 30-year design life in outdoor installations.
- Transformer ONAN cooling with 65°C winding temperature rise rating under IEC 60076 provides design margin for operation in Saudi Arabia's 50°C ambient environment, maintaining transformer life expectancy at full rated load without forced cooling — reducing lifetime operating cost compared to ONAF transformers requiring fan maintenance.
- Compact footprint on minimal civil foundation (concrete pad only, no building required) significantly reduces civil construction cost and urban land take compared to a conventional brick or pre-cast concrete kiosk substation, enabling substation installation in residential development streetscapes with minimal visual impact.
- Modular assembly on factory-built base frame allows the PASS M0 to be repositioned or relocated using a crane if the distribution network layout changes, unlike a permanent civil kiosk substation — providing the flexibility required for phased urban development projects where substation locations are confirmed incrementally.
Industrial Applications in Saudi Arabia
- Residential development distribution substations at ROSHN housing projects and Ministry of Housing residential city developments, where the PASS M0's fast installation timeline allows the electrical distribution network to keep pace with the civil construction programme and enables SEC distribution connection approval for each residential cluster as it is completed.
- NEOM urban district power distribution substations along The Line and Sindalah Island, where the compact PASS M0 footprint minimises land take in densely planned urban areas and the factory-assembly approach allows multiple substation deliveries per week to match the demanding NEOM project construction schedule.
- Red Sea Project resort development substations at Shura Island and other Red Sea Project sites, where the PASS M0 GRP enclosure's coastal corrosion resistance is essential for 30-year service life in the high-humidity salt-air marine environment, and the compact design fits the resort landscaping aesthetic requirements.
- Industrial estate incoming substations at MODON, SIDF, and King Salman Energy Park (SPARK) industrial lot developments, where factory developers require fast power connection for fit-out and production start, and the PASS M0 enables SEC-approved substation commissioning within weeks of lot handover.
- Temporary construction power substations at major infrastructure projects (NEOM, KAIA airport expansion, Riyadh Metro extension), where the PASS M0's relocatable design allows substations to be moved to new construction fronts as the project progresses, reducing the capital cost of temporary construction power infrastructure.
- Commercial development master-planned infrastructure substations at mixed-use developments in Riyadh, Jeddah, and Dammam, where SEC network connection requires ring main unit substations meeting IEC 62271-202 that the PASS M0 delivers with SEC approval documentation, enabling SEC connection approval without custom engineering.
- Telecommunication tower and mobile base station power supply substations for STC, Zain, and Mobily 5G network expansion, where the PASS M0 provides the dedicated MV-to-LV substation required for high-power 5G tower equipment in areas where the existing LV distribution capacity is insufficient for the additional telecom loads.
