RM6-3 — Schneider RM6 24 kV Compact MV Ring Main Unit
The Schneider Electric RM6 is an ultra-compact 24 kV medium-voltage ring main unit sealed for life in SF6 gas, designed for the secondary distribution network connection of medium-voltage customers, compact substations, and secondary substation transformer protection where space is extremely limited and maintenance access is minimal or impossible. The RM6's sealed-for-life design means no scheduled maintenance for the entire 30-year design life — no gas checks, no contact inspections, no lubrication — a compelling advantage for SEC and private utility distribution substations serving thousands of Saudi residential and light commercial customers where maintenance frequency must be minimised. Its three standard functional units — two ring feeder positions and one transformer protection position with either switch-fuse or circuit breaker — are accommodated in a single piece housing that can be transported in standard elevators and installed in compact substation kiosks.
The RM6 provides a 630 A rated ring feeder current and 25 kA short-circuit withstand, covering all distribution transformer ratings up to 2500 kVA on a 13.8 kV or 24 kV ring distribution network. The optional Easergy Protection unit plugs into the RM6's transformer position to add Sepam-equivalent digital overcurrent and earth fault protection with Modbus and IEC 61850 communication — providing smart grid functionality within the sealed RM6 housing without drilling holes or modifying the sealed gas enclosure. Capacitive voltage detection (CVD) test points on all three positions allow site staff to verify live/dead circuit status using a standard voltage indicator without opening any compartment.
In Saudi Arabia, the RM6 is the most widely used compact RMU for residential community distribution substations, small commercial building MV connections, and industrial estate tenant individual MV connections where land space and substation building area are at a premium. ROSHN residential communities across Riyadh, Jeddah, and Al Khobar specify RM6 units for their internal 13.8 kV distribution network substations to maximise land use efficiency on plots where substation buildings compete with residential and amenity uses.
Razz Middle East maintains RM6 RMUs as standard stock in 3-way and 4-way configurations for immediate delivery. We provide SEC documentation packages, CVD verification, Easergy Protection integration, and site installation coordination for Saudi residential, commercial, and industrial distribution substation projects.

Key Features & Benefits
- Sealed-for-life SF6 design requires zero scheduled maintenance for 30 years — no gas pressure checks, no contact inspections — eliminating maintenance visits and costs across thousands of Saudi distribution substations.
- Ultra-compact single-piece housing fits standard elevator dimensions and compact substation kiosks, enabling installation at space-constrained residential compound and commercial property substation locations.
- Capacitive voltage detection (CVD) test points allow site staff to verify live/dead status without opening any compartment, satisfying SEC safety procedure requirements for MV switching operations.
- Easergy plug-in protection unit adds Sepam-equivalent digital overcurrent and earth fault protection with IEC 61850 communication without modifying the sealed gas housing, enabling smart grid upgrade.
- 630 A feeder rating and 25 kA short-circuit withstand covers all distribution transformer ratings up to 2500 kVA on SEC's 13.8 kV ring distribution network without special reinforcement.
- Optional 4-way and 5-way configurations with additional feeder positions extend the standard 3-way RMU to serve multiple transformer connections or bus section points within a single sealed housing.
- Single-manufacturer integration with Sepam protection relays and SM6 extended switchgear creates a consistent Schneider MV product architecture across the full Saudi distribution substation product range.
Industrial Applications in Saudi Arabia
- ROSHN residential community 13.8 kV internal ring distribution network substations in Riyadh, Jeddah, and Al Khobar, where RM6's compact kiosk installation maximises residential plot land use efficiency.
- SEC secondary distribution network 13.8 kV customer connection substations throughout the Kingdom, where RM6's sealed-for-life design minimises maintenance burden on SEC's large distributed substation portfolio.
- Small and medium commercial building MV connection substations in Riyadh's commercial districts, where RM6's compact footprint accommodates the MV switchgear within the basement substation room of the building.
- MODON industrial estate small tenant MV connections at Riyadh and Dammam industrial cities, where RM6 provides metered 13.8 kV connections to tenants with supply demands up to 2500 kVA.
- Rural electrification distribution substation on SEC's rural network expansion programme, where RM6's maintenance-free design eliminates the need for trained switchgear technicians to make periodic visits to remote locations.
- Hospital outpatient facility and clinic satellite MV connections under the Ministry of Health's PHC network, where RM6 kiosks provide standalone MV-to-LV transformer connections without a dedicated switchroom building.
- Saudi university campus secondary substation MV connections, where RM6 units serve individual faculty buildings from the campus 13.8 kV ring without requiring dedicated electrical plant rooms in each building.
