Function

The Siemens 3RT2016-2AF02 is a key component in any electrical control system. Its primary function is to remotely switch a high-power electrical circuit, such as a motor, on and off using a low-power control signal from a PLC, push button, or other control device.

The integrated auxiliary contact provides feedback on the contactor’s status, allowing for interlocking and safety functions within the control system. The spring-loaded terminals ensure the integrity of these control and power connections, even in demanding industrial environments.
