المميزات والفوائد
- Starting current reduction to one-third of DOL starting current during the star period limits supply voltage dip on local distribution panels, meeting ARAMCO, NWC, and SEC requirements for voltage flicker limits on shared distribution feeders.
- Matched three-contactor assembly with factory-set mechanical and electrical interlocks prevents star and delta contactors from closing simultaneously — eliminating the three-phase short circuit risk that exists with individually selected contactor sets.
- Adjustable CT-APS transition timer (3–30 s) allows the changeover delay to be set to match the motor's acceleration time to near-synchronous speed in star, minimising the transition transient current surge at star-to-delta changeover.
- T-series overload relay on the delta contactor monitors full running current in delta configuration, providing thermal overload and phase-failure protection during normal steady-state operation after star-to-delta transition.
- Type 2 IEC 60947-4-1 coordination testing of the three-contactor assembly confirms fault condition performance, satisfying ARAMCO SAES-P-104 and SABIC project engineer requirements for motor starter panel documentation.
- Compatible with AF series contactor universal coil voltage (24–500 V AC/DC), making the star-delta kit suitable for both 220 V AC and 110 V AC control circuit designs without contactor replacement across Saudi Arabia's diverse panel voltage standards.
- Compact DIN rail assembly footprint allows star-delta starter elements to be assembled into standard 600 mm MCC modules alongside overload relay, MCB, and control components without exceeding MCC module depth limits.
التطبيقات الصناعية
- Centrifugal pump motor starters at ARAMCO water injection and crude transfer stations, where Y/D starting reduces the current inrush that would otherwise cause protection relay trips on the 11 kV/400 V transformer secondary feeder.
- HVAC air handling unit supply fan starters in commercial buildings across Riyadh and Jeddah, where Y/D starting limits flicker on the building's LV main switchboard during the frequent fan restart cycles required by HVAC control sequences.
- Water booster pump starters at NWC and MARAFIQ pump stations for motors above 18.5 kW, where the Y/D starting method is specified in the National Water Company's motor control panel engineering standard.
- Cooling tower fan starters at industrial and commercial facilities in Dammam and Al Khobar, where Y/D starting on fans above 22 kW limits the starting current impact on lightly loaded distribution systems during off-peak periods.
- Cement plant conveyor and fan motor starters at Saudi Cement and Qassim Cement plants, where Y/D starters provide economical reduced-voltage starting for conveyor drive motors up to 160 kW without the cost of variable speed drives.
- SABIC utility cooling water pump and wastewater aeration blower starters at Jubail Industrial City, where Y/D starting satisfies SABIC's motor starting current limit requirements without requiring variable frequency drives on non-critical duty services.
- Agricultural irrigation pump starters for large farm and greenhouse operations across Al Qassim and Al Hasa regions, where Y/D starting on 45–90 kW pump motors limits the impact on rural distribution feeder voltage during simultaneous pump starts.
