ABB A5ON2-30-11-84 Contactor

ABB A50N2-30-11-84 Contactor is a three-pole motor starter from ABB’s A50N family, designed to energize and break three-phase loads in industrial control circuits. It uses a 110–120 V AC control coil (coil code 11) and is configured for a standard line-voltage control scheme, with a built-in auxiliary contact arrangement that supports basic control logic and interlock functions. The -84 suffix identifies this legacy catalog version of the A50N2-30-11-84 model. In its common configuration, the main contacts are rated for three-phase switching, making it suitable for energizing motors, pumps, fans, and other inductive loads in commercial and industrial environments when paired with the appropriate control circuit. The unit is designed for operation with 50/60 Hz power systems and is built to withstand the continuity and cycling requirements typical of field-installed motor control hardware, enabling reliable start/stop sequences in conveyors, compressors, and HVAC equipment. When selecting this model, users typically consider the frame size and current class of the A50N2 family, ensuring compatibility with the target motor’s nominal current and the control voltage available in the application. This makes the A50N2-30-11-84 a compact, versatile option for basic three-phase motor switching with integrated auxiliary contact signaling.
