ABB ZA300-81 U 24V Industrial DC Coil Relay Module

ABB ZA300-81 is a replacement coil designed for ABB A210–A300 contactors, delivering 24V to energize the coil. The ZA300-81 variant is specified as a 24V AC coil with a 50 Hz operating frequency, aligning with standard European control voltages and ABB’s ZA300 coil lineup. This coil is used in industrial control panels to activate the contactor’s main contacts, enabling reliable switching of higher-current loads such as motors, pumps, fans, and conveyors in automation and process applications. Key details include the part number ZA300-81 and its compatibility with ABB A210–A300 contactors, providing a direct, interchangeable coil option within ABB’s coil families for consistent performance across typical motor-control and general-purpose control circuits. For exact mounting, terminal configuration, and any power/drive considerations, consult the ABB documentation for ZA300-series coils to ensure proper fitment in your assembly.
