Siemens 3RT2046-3KB40 S3 Power Contactor - 95A, 24V DC Coil
Siemens 3RT2046-3KB40 S3 power contactor, 95A, 24V DC coil.
The Siemens 3RT2046-3KB40 is a 3-pole power contactor designed for AC-3e and AC-3 applications, rated at 95A and 55kW at 400V. This model features a 24V DC control coil with an operating range of 0.8-1.2* Uc and includes an integrated varistor for surge suppression, making it suitable for PLC outputs. It is equipped with 1 normally open (NO) and 1 normally closed (NC) auxiliary contact. The main circuit uses screw terminals, while the control and auxiliary circuits have spring-loaded terminals. This contactor is built in size S3.
This DC-coil power contactor is ideal for applications where a DC control voltage is present or preferred, such as in automated systems controlled by PLCs. The integrated varistor provides protection against voltage spikes, enhancing the longevity of connected equipment. It's commonly used in motor control, industrial automation, and power switching applications.
