Siemens 3RT2018-2BE41 SIRIUS Power Contactor, 16A, 7.5 kW, 60V DC Coil with Spring-Loaded Terminals Original Brand New

Overview

The Siemens 3RT2018-2BE41 is a high-performance SIRIUS series power contactor designed for reliable and efficient switching of electric motors and other loads. This compact and versatile contactor, with a size of S00, is engineered for a broad range of industrial applications. It 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.

The 60 V DC coil ensures a secure and stable control signal, while the innovative spring-loaded terminals provide quick, vibration-proof, and maintenance-free connections. The integrated 1 NO (normally open) auxiliary contact expands its functionality for control and signaling circuits.

Features & Benefit

• Robust Performance: Rated for AC-3e/AC-3 switching of motors up to 7.5 kW (at 400V) and 16 A, providing reliable operation in demanding industrial environments.
• Space-Saving Design: The compact S00 size allows for high-density mounting in control cabinets, optimizing panel space and reducing overall equipment footprint.
• Reliable DC Operation: The 60 V DC coil ensures stable switching, ideal for applications requiring a DC control voltage.
• Fast and Secure Connections: Spring-loaded terminals offer a quick, tool-free wiring solution, ensuring a permanent, gas-tight connection that is resistant to vibration and thermal cycling. This significantly reduces installation time and maintenance efforts.
• Integrated Auxiliary Contact: The built-in 1 NO auxiliary contact simplifies wiring for interlocking, signaling, and control functions, eliminating the need for separate add-on blocks in many applications.
• Versatile Application: Suitable for a wide range of uses including motor control, resistive load switching, and as a component in complex industrial automation systems.
• Part of the SIRIUS Family: As a member of the Siemens SIRIUS modular system, it integrates seamlessly with other SIRIUS components like overload relays and circuit breakers, enabling easy and flexible system design.

Function

• Switches electrical loads, particularly motors, on and off.
• Provides a safe and reliable means of controlling power flow to connected equipment.
• The integrated auxiliary contact facilitates remote signaling of the contactor’s state (ON/OFF) to other control systems or indicators.
• Can be used in conjunction with thermal overload relays (sold separately) to provide comprehensive motor protection.
