Siemens 3RT1064-2AT36 Power Contactor 225A, 110 kW / 400V AC, 3-Pole Original Brand New

Overview

The Siemens 3RT1064-2AT36 is a robust and high-performance SIRIUS 3RT10 series power contactor designed for switching motors and non-inductive loads up to 110 kW at 400 V (AC-3e/AC-3). As a Size S10 contactor, it is engineered for demanding industrial applications requiring reliable operation and high current capacity.

This model features a conventional operating mechanism compatible with both AC and DC control voltages in the 575-600 V range. It includes 3 main poles and 2 NO + 2 NC integrated auxiliary contacts for versatile control circuit integration. The main circuit utilizes busbar connection for high-power distribution, while the control and auxiliary circuits use spring-loaded terminals for fast, vibration-proof wiring.
