Function

A power contactor is an electrically controlled switch used for switching an electrical power circuit. The Siemens 3RT2016-1AN22 works by receiving a 220 V AC signal at its coil terminals (A1-A2). When the coil is energized, it generates a magnetic field that pulls the main contacts together, allowing current to flow to the connected load (e.g., an electric motor). When the coil is de-energized, a spring mechanism separates the contacts, interrupting the power circuit. The integrated 1NC auxiliary contact opens when the main contacts close, providing a signal that the contactor is operational. This functionality is crucial for motor control, safety interlocks, and automated machinery.

Application

• Motor control and protection in industrial machinery
