• Integrated Auxiliary Contacts: The built-in 1 NO + 1 NC auxiliary contacts provide convenient feedback and control signals without the need for additional add-on blocks.

Function

The Siemens 3RT2027-2AK60 functions as an electrically operated switch for a power circuit. When a control voltage of 110 V AC (50 Hz) or 120 V AC (60 Hz) is applied to its coil, it closes the main power contacts, allowing current to flow to the connected load (e.g., a motor).

When the control voltage is removed, the contacts open, interrupting the power. The integrated auxiliary contacts change state simultaneously, providing signals for monitoring or interlocking functions in the control system. The spring-loaded terminals ensure a reliable, maintenance-free connection for the control and power wiring.

Application

• Motor control and protection
• HVAC systems
• Pump and fan control
• Conveyor systems
• Machine tools
• General industrial automation
