Siemens 3RT2016-1DF47 SIRIUS Power Contactor, 9A / 4kW, 110V DC Coil, Size S00 Original Brand New

Overview

The Siemens 3RT2016-1DF47 SIRIUS Power Contactor is a high-performance, 3-pole switching device engineered for reliable motor starting and load switching applications up to 4 kW at 400 V and a rated operational current of 9 A (AC-3e/AC-3). Part of the renowned SIRIUS 3RT2 series, this robust contactor features a low-power 110 V DC coil and is equipped with a pre-installed varistor for effective coil surge suppression. It is built in the compact Size S00 and includes five integrated auxiliary contacts (3 NO + 2 NC), offering superior control and monitoring capabilities.

Benefits & Features

• Enhanced Coil Protection: The plugged-on varistor absorbs voltage spikes during coil de-energization, increasing the lifespan of the coil and protecting control circuit components.
• High Control Flexibility: Includes an integrated block of 3 Normally Open (NO) and 2 Normally Closed (NC) auxiliary contacts, providing immediate access to critical control and feedback signals without requiring external add-ons.
• Robust & Compact Design: The Size S00 construction ensures minimal space requirements in control cabinets while maintaining high mechanical and electrical service life.
• Simple Maintenance: Features a removable auxiliary switch block for quick and easy replacement or modification.
• Versatile Application: Ideal for controlling motors, heating systems, and other general-purpose AC loads in various industrial automation and control panel environments.

Function / Application

The Siemens 3RT2016-1DF47 is primarily used for switching 3-phase AC motors and resistive loads. Its main function is to reliably and safely switch the primary power circuit based on a low-voltage DC control signal (110 V DC). Common applications include:

1. Motor starter combinations (in conjunction with an overload relay).
2. Switching lighting systems, pumps, and fans.
3. Integration into industrial automation systems and control panels requiring DC control.
