Function

The 3RT2024-2BB44 functions as an electromechanically operated switch used to safely control electric motors or other power loads (like heating circuits). When the 24 V DC control voltage is applied to the coil, the main contacts close, supplying power to the load. The auxiliary contacts provide feedback (status) to a programmable logic controller (PLC) or are used for controlling other components in a circuit.
