Siemens SIRIUS 3RT1064-2NP36 Power Contactor 225A, 110kW, AC/DC 200-277V, S10, Spring-Loaded Terminals Original Brand New

Overview

The Siemens 3RT1064-2NP36 is a high-performance, 3-pole power contactor from the modular SIRIUS 3RT10 series, designed for reliable switching of electric motors up to 110 kW at 400 V (AC-3e/AC-3). This robust contactor is part of the S10 size family, known for its compact design and high contact reliability, even in demanding industrial applications.

It features a wide-range electronic operating mechanism (drive), accepting both AC and DC control voltages from 200-277 V, and is equipped with a dedicated 24 V DC PLC input for modern automation system integration. The main circuit utilizes busbar connections for high-current applications, while the control and auxiliary circuits feature spring-loaded terminals for fast, vibration-proof, and maintenance-free wiring.
