Siemens 3RT2016-1DM47 SIRIUS Power Contactor, 9A, 220V DC Coil Original Brand New

Overview

The Siemens 3RT2016-1DM47 is a high-performance 3-pole power contactor from the globally recognized SIRIUS 3RT20 series, specifically engineered for switching motors (AC-3e/AC-3 category). Rated for $9\text{ A}$ and up to $4\text{ kW}$ at $400\text{ V}$, this compact contactor is built in the small Size S00 frame. It features a reliable $220\text{ V DC}$ operating mechanism with an integrated, plugged-on varistor for surge suppression, ensuring coil protection and minimizing operational downtime. The unit is equipped with screw terminals for robust and secure wiring.

• Enhanced Coil Protection: The built-in varistor suppresses voltage spikes, prolonging the lifespan of the coil and providing reliable operation in DC control circuits.
• High Control Flexibility: Includes an integrated $3\text{ NO}+2\text{ NC}$ auxiliary switch configuration, with the added benefit of a removable auxiliary switch for maintenance or modification.
• Space-Saving Design: The compact S00 size allows for high packing density and efficient use of space within control cabinets.
• Simplified Wiring: Robust screw terminals ensure a secure, high-contact connection for both main and auxiliary circuits.

Function

The Siemens 3RT2016-1DM47 functions as a remotely controlled switching device. When the $220\text{ V DC}$ control voltage is applied to the coil, the main contacts close, connecting the $400\text{ V}$ motor load to the power supply. The five auxiliary contacts ($3\text{ NO}+2\text{ NC}$) simultaneously change state, providing feedback, interlocking, or control signals for the overall automation system. Its robust design ensures a long mechanical and electrical service life, making it a dependable choice for industrial automation and control panels.
