Siemens 3RT2023-1AM20 Three-Phase Power Contactor

Siemens 3RT2023-1AM20 is a three-pole power contactor in the 3RT2 family, designed for AC-3 duty and rated to switch up to 9 A. It operates from a 208 V AC coil at 60 Hz, enabling direct use with common 208/60 Hz control circuits, and it includes three normally open auxiliary contacts for signaling or interlocking alongside the main contact set. In motor-control applications, the unit supports up to 4 kW at 400 V (AC-3), giving reliable three-phase motor switching for devices such as pumps, fans, and conveyors. The 3-pole construction and 208 V coil configuration make this model suitable for compact control panels where space and compatibility with standard Siemens auxiliary blocks and coil supplies are important.
