Function

The Siemens 3RT2035-1AD00 power contactor serves as an electrically controlled switch used for switching an electrical power circuit. It is primarily used for the remote control of three-phase motors. When the 42 V AC control voltage is applied to the coil, the main contacts close, allowing the high-current power circuit to flow to the load.

The auxiliary contacts change their state simultaneously, providing feedback to the control system or interlocking with other components. This makes it an essential component in motor starters, control panels, and automation systems.

Application

• Motor control and starting
• Switching resistive and inductive loads
• HVAC systems
• Pumps and compressors
• Conveyor systems
• General industrial automation
