Socomec ATyS 6D 160A 4-Pole Automatic Transfer Switch

The Socomec ATyS 6D 160A 4-Pole Automatic Transfer Switch (model 3120 6400) is an IEC 60947-6-1 compliant automatic transfer switch engineered for medium-duty commercial and industrial applications requiring reliable grid-to-generator changeover at 160A continuous rating. The ATyS 6D 160A occupies a critical niche in the Saudi Arabian market: it bridges the gap between small residential-scale ATS units and full motor-operated MV switchgear, making it the standard selection for retail mall sub-boards, hotel floor distribution boards, hospital wing feeders, and industrial plant room distribution panels where loads run from 50 kW to approximately 80 kW. Its 4-pole architecture satisfies SEC and ARAMCO engineering standards for installations requiring full neutral switching, and the unit is pre-approved under several ARAMCO and Ministry of Health engineering specification packages.

The 3120 6400 incorporates Socomec's advanced source quality monitoring engine, which evaluates SEC grid supply and generator output across multiple parameters simultaneously: phase-to-neutral and phase-to-phase voltage for all three phases, supply frequency (with adjustable deviation windows around 50 Hz), phase sequence, and phase loss detection. This multi-parameter monitoring prevents premature transfer to a generator with a faulty AVR, or retransfer to a grid supply that is still in a brownout condition — both failure modes that cause expensive load equipment damage in facilities where power quality events are common, such as industrial zones in Jubail and Dammam or areas served by overhead distribution networks in rural Saudi regions.

In the Saudi market, ATyS 6D 160A units are a standard product in hospital backup systems at King Fahad Medical City, Saudi German Hospital networks, and Ministry of Health district hospitals across the Kingdom. The unit's compliance with NFPA 110 Level 1 transfer switch requirements — in addition to IEC standards — makes it acceptable to hospital engineers who reference both international codes, a common situation in Saudi Arabia's mixed-standards environment. For NEOM project MEP contractors, the ATyS 6D series provides the documented SEC-compatible transfer switch specification required in Smart City building codes.

Razz Middle East maintains stock of common ATyS 6D ratings including the 160A model and can deliver to any location in Saudi Arabia within standard lead times. Our applications team provides generator compatibility checks, panel layout design, and commissioning support as part of the standard supply package for qualified contractors and end users across Riyadh, Jeddah, Dammam, Khobar, Jubail, and Yanbu.
