Function

The Siemens 3RT2015-2VB42 power contactor is primarily used for switching and controlling motors and other resistive or inductive loads. When the 24V DC coil is energized, the main contacts close, allowing power to flow to the connected equipment. The single NC auxiliary contact can be used for feedback, interlocks, or signaling purposes within the control circuit. This contactor is a crucial component for:

• Starting and stopping electric motors.
• Controlling lighting circuits.
• Managing heating elements.
• Automated machinery and process control systems.

Technical Specification

• Rated Insulation Voltage: 690 V
• Degree of Protection: IP20 (front side)
• Operating Temperature: -25 to +60 °C
• Mounting: Snap-on mounting on standard mounting rail
• Weight: Approximately 0.2 kg
