SIRIUS 3RT2015-1BW42 Power Contactor, 7A, 3kW, 3-Pole, 48V DC Coil, Size S00, 1NC Aux Original Brand New

Overview

The Siemens 3RT2015-1BW42 power contactor is a high-performance switching device from the SIRIUS 3RT20 series, designed for reliable switching of electric motors and other loads up to 7 A (AC-3e/AC-3) and 3 kW at 400 V. This compact, 3-pole contactor is engineered for use in industrial control systems and motor starter applications. Featuring a low-power consumption 48 V DC coil, a standard 1 NC integrated auxiliary contact, and secure screw terminals, the size S00 unit offers a space-saving and robust solution for demanding environments. It is approved worldwide and is designed for compatibility within the SIRIUS modular system.

Benefit

1. High Reliability: Part of the trusted Siemens SIRIUS modular system, ensuring high contact reliability and long electrical service life.
2. Space-Saving Design: The compact Size S00 makes it ideal for installations where cabinet space is limited.
3. Low Energy Consumption: The 48 V DC coil provides efficient and reliable operation.
4. Easy Wiring: Secure screw terminals simplify installation and maintenance.
5. Global Compatibility: Worldwide approvals (e.g., IEC, UL/CSA) allow for use in a wide range of international applications.
6. Integrated Auxiliary Contact: The built-in 1 NC auxiliary contact reduces complexity and wiring effort.

Function

• Motor Switching: Safely and reliably switch the main current paths for 3-phase AC motors (AC-3e/AC-3 applications).
• Load Control: Suitable for general resistive and non-inductive loads (AC-1 applications up to 18 A).
• Signal Feedback: The integrated 1 NC auxiliary contact provides feedback on the contactor’s switching status to a control system (e.g., PLC or relays).
