Siemens 3RT2018-2KB42-0LA0 SIRIUS 3RT20 Contactor, 16 A, 24 V DC, 1 NC, S00, Spring-loaded Terminal Original Brand New

Overview

The Siemens 3RT2018-2KB42-0LA0 is a high-performance traction contactor from the SIRIUS 3RT20 series, specifically engineered for reliable switching in DC applications. With a compact S00 frame size, this 3-pole contactor is rated for 16 A and 7.5 kW at 400 V (AC-3e/AC-3), making it ideal for controlling motors and other loads in challenging environments.

The integrated suppressor diode and plugged-on series resistor ensure enhanced protection and extended service life. Featuring a 24 V DC control voltage with a wide operating range of 0.7-1.25*Uc, it offers exceptional stability and adaptability. The 1 NC auxiliary contact and spring-loaded terminals simplify wiring and installation, providing a secure and vibration-resistant connection.
