Siemens 3RT2018-1BE42 Power Contactor, 16A, 7.5kW, 60V DC, S00 Original Brand New

Overview

The Siemens 3RT2018-1BE42 Power Contactor is a high-performance 3-pole switching device from the SIRIUS 3RT2 series, designed for controlling electric motors and other loads. Part of the modular SIRIUS system, this contactor offers a compact, reliable solution for demanding industrial applications. It is rated for $16\text{ A}$ in $\text{AC-3e}/\text{AC-3}$ duty and is suitable for motor switching up to $7.5\text{ kW}$ at $400\text{ V}$. Its $60\text{ V DC}$ operating coil provides dependable switching, and the Size S00 form factor ensures efficient use of space in control panels.

Benefit

• Compact Design (Size S00): Space-saving form factor for efficient panel integration.
• High Reliability: Part of the proven Siemens SIRIUS modular system, ensuring excellent contact reliability and long mechanical life (up to $30\text{ million}$ operating cycles).
• Global Standard Compliance: $\text{IEC}$ and $\text{UL}/\text{CSA}$ approved for worldwide application.
• DC Control Versatility: $60\text{ V DC}$ coil voltage provides stable and consistent operation in DC control circuits.
• Easy Integration: Integrated $1\text{ NC}$ auxiliary contact simplifies wiring and interlocking with other control components.

Function

The 3RT2018-1BE42 is a primary component for motor and load control. When the $60\text{ V DC}$ control voltage is applied to the coil, it electromagnetically closes the three main power contacts, allowing current to flow to the motor or load. The integrated $\text{NC}$ auxiliary contact simultaneously opens, providing a signal for the control circuit or for safety interlocks. The screw terminals provide a robust and secure connection for both the main power and control wiring.
