Siemens 3RT2016-1DW47 SIRIUS Power Contactor, 9A, 4kW, 48V DC with Varistor, 3NO+2NC Aux, Screw Terminal Original Brand New

Overview

The Siemens 3RT2016-1DW47 is a high-performance SIRIUS power contactor designed for reliable and efficient control of electric motors and other loads up to 4 kW. This 3-pole contactor is rated for 9 A and 400 V (AC-3e/AC-3) and is engineered for use in demanding industrial environments.

Its compact Size S00 footprint saves valuable panel space, while the included 48 V DC coil with a built-in varistor provides superior protection against voltage spikes, ensuring a long operational life. The integrated 3 NO + 2 NC auxiliary contacts offer enhanced flexibility for interlocking, signaling, and control circuits. Featuring robust screw terminals, installation and maintenance are straightforward and secure.

Key Features & Function

• Motor Control: Ideal for switching motors with a rating up to 4 kW at 400 V.
• 3-Pole Design: Provides reliable switching for three-phase applications.
• Integrated Varistor: The 48 V DC coil comes with a plugged-on varistor, which effectively dampens surge voltages, protecting the contactor and connected control electronics.
• Versatile Auxiliary Contacts: The 3 Normally Open (NO) and 2 Normally Closed (NC) auxiliary contacts can be used for feedback, control logic, and safety interlocking, eliminating the need for separate auxiliary blocks.
• Removable Auxiliary Switch: This feature allows for easy configuration and replacement of the auxiliary contacts, simplifying maintenance.
• Screw Terminals: Ensures a strong, vibration-proof connection, providing excellent reliability in industrial settings.
