Siemens 3RT2047-3NB30 SIRIUS Power Contactor, 110A, 55kW, 20-33V AC/DC Coil, S3 Size, Spring-Loaded Terminal Original Brand New

Overview

The Siemens 3RT2047-3NB30 SIRIUS Power Contactor is a robust and compact solution for switching motors and industrial loads up to 55 kW at 400 V. Part of the proven SIRIUS 3RT2 series, this 3-pole contactor is designed for demanding AC-3e/AC-3 applications with a rated operational current of 110 A. Its versatility is enhanced by a wide-range 20-33 V AC/DC control voltage and an integrated varistor for coil protection, simplifying your control circuit design.

Benefits & Features

• Reliable and Safe Switching: Designed for high-performance motor control with a high contact reliability and integrated varistor protection against voltage surges.
• Reduced Wiring Time: The innovative spring-loaded terminals for the control and auxiliary circuits ensure fast, vibration-proof, and maintenance-free connection. The main power circuit uses reliable screw terminals.
• Global Compatibility: Approved for worldwide use (e.g., IEC and UL/CSA) and is IE3/IE4-ready, making it ideal for international industrial applications.
• Space-Saving Design: Size S3 offers a compact footprint despite its high 110 A current rating, integrating seamlessly into modular control panels (SIRIUS modular system).

Application

The Siemens 3RT2047-3NB30 is the perfect component for reliable and efficient switching of:

• Standard 3-phase AC Motors (Direct-on-Line starting)
• Heating and Lighting Systems
• Industrial Machinery and Plants
• Other resistive and highly inductive loads in low-voltage industrial control.
