Siemens 3RT2016-1DE47 Power Contactor 9A, 4kW, 400V, 3-Pole DC, 60V Coil, Varistor, 3NO+2NC Contacts Original Brand New

Overview

The Siemens SIRIUS 3RT2016-1DE47 is a high-performance, 3-pole power contactor designed for the switching of electrical loads, particularly motors. Part of the compact SIRIUS 3RT2 series (size S00), this contactor offers exceptional reliability and a long mechanical service life (typically 30,000,000 switching cycles). It is rated for AC-3e/AC-3 switching of up to 9 A or 4 kW at 400 V.

A key feature is the integrated 60 V DC control voltage with a plugged-on varistor for coil protection against switching surges, ensuring greater system stability. The unit comes complete with an advanced auxiliary switch configuration of 3 normally open (NO) and 2 normally closed (NC) contacts, which are easily removable for maintenance or replacement. Connection is made via secure screw terminals.
