Siemens 3RT2015-1AD01 Power Contactor, 7A, 3kW, 42V AC Coil, SIRIUS 3RT2 Original Brand New

Overview: Siemens SIRIUS 3RT2015-1AD01 Power Contactor

The Siemens 3RT2015-1AD01 is a compact and high-performance 3-pole power contactor from the SIRIUS 3RT2 family, specifically designed for switching motors and other resistive loads in industrial control applications. This size S00 contactor provides a robust solution for load feeders, offering convincing performance with a high degree of contact reliability. It features a control coil voltage of 42V AC for both 50Hz and 60Hz operations and utilizes secure screw terminals for main and auxiliary circuits.

Benefit

1. Compact Design (Size S00): Space-saving dimensions allow for high-density installation in control panels and cabinets.
2. High Performance and Reliability: Part of the modular SIRIUS system, ensuring coordinated products and consistent, reliable operation for switching motors.
3. Versatile Application: Suitable for switching motors (AC-3/AC-3e) and general resistive loads (AC-1) up to 7A/3kW.
4. Integrated Auxiliary Contact: The built-in 1 NO contact simplifies wiring and reduces the need for external auxiliary switch blocks for basic control loops.
5. Global Compliance: Approved for worldwide use (e.g., IEC and UL/CSA) and is IE3/IE4-ready for energy-efficient motor applications.
6. Secure Wiring: Robust screw terminals ensure reliable, high-integrity electrical connections.

Function

The Siemens 3RT2015-1AD01 is a primary component in a motor control circuit. Its function is to electrically switch the power (main) circuit to an electric motor or other load. The low-voltage 42 V AC coil is energized by a control signal (e.g., from a PLC or push button), which closes the three main contacts, applying power to the motor. The integrated 1 NO auxiliary contact can be used for feedback (status signaling), interlocking, or controlling other circuits in the automation system.
