Siemens 3RT2018-2BM42 SIRIUS Power Contactor, 16A, 7.5 kW, 220V DC Coil, Size S00 Original Brand New

Overview

The Siemens 3RT2018-2BM42 is a high-performance SIRIUS power contactor designed for robust motor and load control applications. This 3-pole contactor is rated for AC-3e/AC-3 operation, handling currents up to 16 A and motor power up to 7.5 kW at 400 V. Its compact S00 frame size makes it an ideal solution for space-constrained industrial panels.

Featuring a 220 V DC control coil and convenient spring-loaded terminals, this contactor offers reliable performance and easy, quick installation without the need for specialized tools. An integrated 1 NC auxiliary contact provides essential feedback for control circuits and interlocking functions.

Key Benefit

• High Performance: Optimized for AC-3e/AC-3 switching, ensuring efficient and reliable control of motors and resistive loads.
• Space-Saving Design: The compact S00 size allows for high-density panel layouts, reducing overall cabinet footprint.
• Fast & Secure Installation: Spring-loaded terminals provide a vibration-proof and gas-tight connection, significantly reducing wiring time and maintenance.
• Versatile Application: Suitable for a wide range of industrial applications, including motor control, lighting systems, and heating loads.
• Integrated Auxiliary Contact: The built-in 1 NC contact simplifies circuit design for status indication or interlocking.
• Energy Efficient: The 220 V DC coil offers lower power consumption compared to AC alternatives, contributing to energy savings.

Function

• Motor Control: Switches on and off 3-phase AC motors up to 7.5 kW.
• Load Switching: Used for switching other electrical loads, such as transformers, capacitors, and lighting.
• Remote Operation: Activated by a 220 V DC signal, allowing for remote control from PLCs, relays, or pushbuttons.
• Safety & Interlocking: The 1 NC auxiliary contact can be used in safety circuits to ensure machinery is not operated under unsafe conditions.
