ABB DOL Motor Starter Kit (AF + T Series)

ABB direct-on-line (DOL) motor starter kits combine a factory-selected and pre-coordinated AF series electronically actuated contactor with a T series thermal overload relay and all necessary DIN rail accessories into a single part number, delivering a Type 2 IEC 60947-4-1 coordinated motor starting assembly that panel builders can order, receive, and assemble without separate component selection work. The kit format covers motor powers from 0.25 kW to 45 kW at 400 V across the AF09-to-AF65 contactor range, with the T-series overload relay current range matched to the exact motor power selected. Coil voltage options of 24 V DC, 110 V AC, and 220 V AC are available to match every standard Saudi Arabian control circuit voltage, and accessories including auxiliary contact blocks, mechanical interlock frames, and mounting rails are included where required for the selected starting duty.

The AF series contactor at the heart of the DOL kit introduces a significant advance over conventional coil-wound contactors: the AF contactor's electronic actuator accepts any voltage between 24 and 500 V AC/DC simultaneously without coil or coil resistance changes, making it genuinely power-supply agnostic. Once energised, the AF contactor's hold current drops to 5–10% of its pull-in current due to the electronic actuator's adaptive hold feature, reducing control circuit power consumption by 80–90% compared to conventional contactors — a meaningful energy saving across the thousands of motor starters running continuously in Saudi Arabia's pump, HVAC, and process facilities. The AF contactor's electronic surge suppression eliminates the need for external RC snubber circuits across contactor coil terminals that are routinely fitted to protect PLC output modules on conventional contactor installations.

DOL starters are the most common motor starting solution in Saudi Arabia's industrial and commercial sectors by sheer number of installations — every fan, pump, and conveyor motor that does not justify a variable speed drive or soft starter uses a DOL starter as its primary starting and protection element. ARAMCO, SABIC, NWC, and SEC all have standard motor control center designs that specify ABB AF+T DOL starter assemblies for their MCC outgoing motor feeder modules. Panel builders in Riyadh's Al-Malaz industrial zone, Jeddah's southern industrial area, and Dammam's industrial city assemble MCC panels with ABB DOL kits as their default motor starter component. The Type 2 coordination documentation provided with each kit satisfies the project engineer's requirement to demonstrate that the contactor and overload relay combination has been tested to IEC 60947-4-1 for fault condition performance without endangering personnel.

Razz Middle East maintains stock of ABB DOL starter kits from AF09 (0.25–4 kW) through AF65 (18.5–45 kW) in 24 V DC and 220 V AC coil versions, with complete Type 2 coordination tables and IEC 60947-4-1 test certificates included with every kit. We supply single kits for maintenance and bulk packs for panel builders, with same-day dispatch and SAR pricing.
