Function

The Siemens 3RT2018-2AV01 power contactor is an electromechanical switch used for remotely controlling and switching a power circuit. When the 400 V AC control voltage is applied to the coil, it creates a magnetic field that closes the main power contacts, allowing current to flow to the connected motor or load. The integrated auxiliary contact changes state at the same time, providing a signal that the main contacts have closed. This makes it an essential component for motor starters, heating circuits, and lighting systems.

Application

• Motor control for pumps, fans, compressors, and conveyors.
• Industrial machine automation.
• Heating and cooling systems.
• Lighting control systems.
• General-purpose switching of resistive and inductive loads.
