ABB AF16Z-30-01-21 Three-Phase Low-Voltage Power Contactor

ABB AF16Z-30-01-21 is a three-pole AF Series low-voltage power contactor designed to switch three-phase motors and loads up to 30 A at voltages up to 690 V AC. It provides three main normally open contacts and one normally closed auxiliary contact for signaling or interlock functions, with a coil that accepts 24–60 V AC or 20–60 V DC for versatile control options. The unit is engineered for compact panel integration, measuring 86 × 45 × 77 mm and weighing about 0.31 kg, with screw-terminal connections and IP20 protection on both coil and main circuitry. It offers low holding power (as little as 1.7 W) and built-in surge suppression to simplify wiring and improve reliability in automation circuits. Electrical ratings include Ie of 30 A at 690 V (at 40–60 °C; 26 A at 70 °C), AC-3 motor loads around 18 A at 415–440 V (decreasing at higher voltages), and AC-23a up to 9 kW at 415–500 V or 4 kW at 230 V, making it suitable for a range of motor-start and load-switching applications. The AF16Z-30-01-21 also supports AC-1 general-use operation up to 30 A and is rated for 50/60 Hz; it complies with IEC/EN 60947-1 and 60947-4-1, and holds UL/CSA recognition for broader electrical-system compatibility. Features such as mirror, mechanically linked contacts and optional integrated control options enhance reliability by ensuring synchronized opening and closing, while the screw terminals and robust construction suit demanding industrial environments and machine-building workflows.
