MCset-C — Schneider MCset 24 kV Metal-Clad HV/MV Switchgear
The Schneider Electric MCset is a 24 kV metal-clad, withdrawable vacuum circuit breaker switchgear system for primary distribution substations and industrial power distribution applications requiring the highest level of electrical and mechanical safety, designed with fully compartmentalised bus, cable, and circuit breaker sections with metal barriers between all live compartments, achieving IEC 62271-200 PM (partition metallic) accessibility category that physically prevents personnel access to any live compartment during normal operation. MCset's withdrawable circuit breaker design allows the VCB unit to be racked out — under Sepam relay supervision — from the panel while adjacent bays remain fully energised, enabling live switchgear maintenance without a full plant shutdown. This live maintenance capability is particularly valued at continuous process plants in Saudi Arabia where a full HV shutdown to access a single faulty circuit breaker can cost millions of SAR in lost production.
The MCset incorporates Schneider's EasyPact EVC vacuum circuit breaker rated for 25 kA short-circuit withstand and 1250 A continuous current, with a 10,000-cycle maintenance interval — three times the interval of equivalent SF6 puffer type circuit breakers. The internal arc resistance classification IAC A FL, tested per IEC 62271-200, ensures that an internal arc fault event is contained within the switchgear enclosure, protecting personnel in the switchroom from the lethal blast effects of HV arc faults. Schneider's EcoStruxure Power integration via the Sepam protection relay provides real-time protection, measurement, and condition monitoring data for the substation automation system.
In Saudi Arabia, MCset primary distribution switchgear is specified for 33 kV and 13.8 kV primary substations at ARAMCO's Dhahran and Jubail refining and petrochemical complexes, at SABIC's cracker and utilities facilities in Jubail Industrial City, and at SEC's primary 33 kV/13.8 kV switching stations serving industrial customers. NEOM's primary utility substations require MCset-class metal-clad switchgear to satisfy the advanced operational and maintenance standards of the smart city's infrastructure management organisation. Ma'aden's mining primary substations at Wa'ad Al-Shamal specify MCset for its arc-resistant protection in the high-dust, high-fault-level environment of mineral processing facilities.
Razz Middle East works with major Saudi EPC contractors to supply MCset switchgear with full ARAMCO and SEC documentation, factory acceptance testing witness, and on-site commissioning by Schneider-certified MV switchgear engineers. We provide long-term service contracts including annual maintenance, protection relay settings management, and EcoStruxure Power subscription for critical Saudi industrial and utility primary substation clients.

Key Features & Benefits
- Withdrawable vacuum circuit breaker under Sepam relay supervision allows live maintenance of individual bays while adjacent bays remain energised, eliminating costly full plant HV shutdowns at Saudi continuous process facilities.
- IAC A FL internal arc-resistant classification contains arc fault blast within the switchgear enclosure, protecting switchroom personnel at ARAMCO, SABIC, and NEOM primary substation facilities.
- PM (partition metallic) accessibility category physically prevents personnel access to any live compartment during normal operation — the highest safety standard for primary substation switchgear.
- EasyPact EVC vacuum circuit breaker with 10,000-cycle maintenance interval is three times the maintenance interval of equivalent SF6 puffer types, reducing maintenance cost over the 30-year substation lifetime.
- 25 kA short-circuit withstand rating covers the fault level of Saudi 132 kV/33 kV primary transformer secondary outputs, without special switchgear reinforcement for standard transformer kVA ratings.
- EcoStruxure Power integration via Sepam relay provides real-time bay status, protection event records, and condition monitoring data for substation automation systems and asset management platforms.
- Modular lineup architecture allows extension with additional feeder, bus section, and bus VT measurement bays without modifying existing bays, supporting Saudi industrial substation capacity expansion projects.
Industrial Applications in Saudi Arabia
- ARAMCO refinery and petrochemical primary distribution switchgear at Dhahran, Ras Tanura, and Jubail, where MCset withdrawable VCB enables live maintenance without loss of production at continuous process plants.
- SABIC cracker and utilities facility primary substation at Jubail Industrial City, where MCset IAC A FL arc resistance satisfies SABIC's engineering standard for switchroom personnel safety.
- SEC primary 33 kV/13.8 kV switching station switchgear for industrial customer connections, where MCset is the preferred metal-clad switchgear in SEC's approved product specifications.
- NEOM utility primary substation switchgear for The Line and Sindalah Island infrastructure, where MCset's PM accessibility category and smart monitoring integration satisfy NEOM's advanced asset management requirements.
- Ma'aden mining primary substation at Wa'ad Al-Shamal, where MCset withstands the high dust loading and vibration of the mineral processing environment and provides live maintenance capability for the 24/7 mining operation.
- Saudi Aramco Gas primary distribution switchgear at Haradh and Hawiyah gas processing plants, where MCset handles the high fault levels of large gas turbine generator bus connections.
- Large hospital and healthcare facility primary substation at Ministry of Health hospital projects, where MCset IAC A FL protection and withdrawable maintenance capability satisfy the continuous availability requirements of critical healthcare infrastructure.
