Siemens 3RT2046-1AV04 SIRIUS Power Contactor, 95A AC-3, 45kW, 400V AC Coil, 3-Pole, S3, 2 NO + 2 NC Aux Original Brand New

Overview

The Siemens 3RT2046-1AV04 is a high-performance, 3-pole power contactor from the globally renowned SIRIUS 3RT2 series. Engineered for reliability in demanding industrial applications, this device is perfectly suited for switching motors and non-resistive loads up to 45 kW at 400 V (AC-3e/AC-3 rated). Featuring a compact Size S3 design, it integrates seamlessly into modern control panels and provides a robust solution for motor control applications.

Function & Application

The 3RT2046-1AV04 contactor serves as the primary switching element in motor starters, load feeders, and general industrial control systems. It is designed for:

• Motor Switching: Safely connecting and disconnecting three-phase asynchronous motors (AC-3/AC-3e operation).
• Controlling Non-Resistive Loads: Switching of lighting, heating, and capacitor banks.
• Integration: Being part of the SIRIUS modular system, it is easily combined with other SIRIUS components like overload relays (e.g., SIRIUS 3RU2) and circuit breakers to form complete, reliable motor starters.

Benefits & Features

• High Performance: Rated for 95 A (AC-3) and capable of handling a 45 kW motor load at 400 V, providing ample power for mid to large-scale industrial machinery.
• Integrated Auxiliary Contacts: Includes a robust set of 2 Normally Open (NO) and 2 Normally Closed (NC) auxiliary contacts, simplifying control circuit wiring and status indication. The auxiliary switch is removable for flexible configuration.
• Reliable Connection: Equipped with secure and widely used screw terminals for main and auxiliary circuits, ensuring a stable and long-lasting electrical connection.
• Global Compliance: The SIRIUS 3RT2 series is internationally recognized and approved (e.g., IEC, UL/CSA), making it suitable for global machinery export.
• Compact S3 Design: Optimized design for maximum performance in a small footprint, saving valuable space within control cabinets.
