Siemens 3RT1965-5AV32 Changeover Operating Mechanism for 3RT106/3RT146 Contactors, 380-420V AC/DC, Spring-Type Terminal Original Brand New

Overview

The Siemens 3RT1965-5AV32 is a high-performance changeover operating mechanism designed as a spare part or accessory for the SIRIUS 3RT1 series power contactors, specifically models 3RT106 and 3RT146 (Size S10). This essential component, often referred to as a withdrawable coil or plug-in coil, provides reliable AC/DC operation for the contactor control circuit. It supports a wide control supply voltage range of 380 to 420 V (at 50…60 Hz AC or DC) and utilizes robust spring-type terminals (Cage Clamp) for fast, vibration-proof wiring. The operating mechanism is switchable between Standard and Economy circuits for versatile power management.

Function

The 3RT1965-5AV32 Changeover Operating Mechanism is essentially the heart of the compatible contactor. When the specified control voltage (380-420V AC/DC) is applied, the internal solenoid coil generates a magnetic force. This force moves the contactor’s armature, which in turn closes or opens the main power contacts. By having both a Standard and Economy circuit option, it allows the contactor to be activated with full power (Standard) and then maintained in the closed position with reduced power (Economy) to minimize heat generation and energy costs.
