ABB CL2-523G Three-Phase Contactor 24V DC Coil

ABB CL2-523G is a compact pilot light with an integrated LED, intended to provide immediate status indication on electrical control panels. Housed in ABB’s grey CL2 signaling housing, it accepts a 24V AC or DC supply, a versatility that aligns with common low-voltage control circuits in industrial equipment. The built-in LED offers bright, long-life illumination with low current draw, delivering reliable visibility in panel-wired setups without the need for separate lamp replacements. As part of ABB’s CL2 signaling line, the CL2-523G serves as a visual indicator for machine or process status — for example signaling PLC outputs, motor-start conditions, or the activation of control relays in automation environments. This model’s design emphasizes compact integration with other CL2 components, enabling straightforward deployment in standard control cabinets. The CL2-523G is referenced in ABB’s minikatalog under low-voltage products and is described as a pilot light with integrated LED, grey housing, and 24V AC/DC compatibility, confirming its role as an indicator device rather than a switch or power-controlling module.
