Siemens 3RT2045-3AP06 SIRIUS Power Contactor, 80A, 37kW, 230V AC Coil, Screw/Spring Terminals, Size S3 Original Brand New

Overview

The Siemens 3RT2045-3AP06 is a high-performance, 3-pole SIRIUS 3RT2 Power Contactor designed for reliable switching and control of electric motors, especially in demanding industrial applications. This robust device operates under the IEC utilization categories AC-3e/AC-3, making it perfectly suited for standard and energy-efficient motors (IE3/IE4 ready).

Featuring a rated operational current of 80 A and a maximum power rating of 37 kW at 400 V, this contactor is built for heavy-duty use. It is a Size S3 unit with a nominal control supply voltage of 230 V AC at 50 Hz.

A key feature of the 3RT2045-3AP06 is its combination of connection technologies: the main circuit utilizes screw terminals for robust power connections, while the control and auxiliary circuits employ efficient spring-loaded terminals for fast, vibration-proof wiring. It includes pre-assembled auxiliary contacts: $2\text{ NO}+2\text{ NC}$ (Normally Open + Normally Closed).
