ABB DRAF09-11U Industrial Variable Frequency Drive

ABB DRAF09-11U is an enclosed direct-on-line motor starter that couples an AF09-30-10-11 3-pole contactor with protective hardware to command 3‑phase motors up to 690 V AC. Delivered assembled and wired, it features an IP66 and 4X plastic enclosure with double insulation, engineered for challenging industrial environments. The unit uses a separate AC control supply for UL starters, specifically 24–60 V at 50/60 Hz, and provides hands-on control with a green flush “I” ON button and a red protruding “O/RESET” button. Four cable ingress/egress knockouts offer flexible wiring options, and the starter includes a CB5‑10 start contact block plus termination points for protective earth and neutral conductors. The DRAF09‑11U configuration accommodates an overload relay, with TF42 rated overloads ordered separately and matched to the motor’s nominal current. Catalogued under ABB part 1SBK134238R1100 as the DRAF09-11U 24-60V50/60HZ, this unit is designed for reliable direct-start control of industrial motors in applications such as pumps, fans, conveyors, and other lines where a compact, pre-wired starter is advantageous.
