Siemens 3RT2016-1MB41-0KT0 SIRIUS Power Contactor, 9A, 4kW, 24V DC, 1NO Aux, Screw Terminal Original Brand New

Overview

The Siemens 3RT2016-1MB41-0KT0 is a high-performance SIRIUS power contactor designed for reliable switching of motors and other industrial loads up to 4 kW at 400 V. As part of the SIRIUS 3RT2 series, this compact size S00 contactor is engineered for demanding applications, ensuring long-term stability and operational safety. Its advanced 24V DC coil technology provides a wide operating range, making it highly versatile for various control systems.

Key Features and Benefit

• High Performance: Capable of handling loads up to 9 A (AC-3e/AC-3) and 4 kW at 400 V, making it suitable for a wide range of motor control and switching applications.
• Energy Efficient: The 24V DC coil offers a wide control voltage range of 0.85 to 1.85 times the nominal voltage (Uc), reducing energy consumption and providing stable operation even with voltage fluctuations.
• Reliable and Durable: Engineered with robust materials and a compact design, the 3RT2016-1MB41-0KT0 ensures a long electrical and mechanical lifespan, minimizing maintenance needs.
• Integrated Auxiliary Contact: Features a built-in 1 NO (normally open) auxiliary contact, allowing for simple integration into control and signaling circuits without the need for additional modules.
• Secure Connection: Equipped with secure screw terminals for quick, reliable, and maintenance-free wiring connections, saving installation time.
• Compact Design: The S00 frame size makes it ideal for use in space-constrained control cabinets and panel installations.
• Safety and Compliance: Designed and manufactured to the highest international standards, including AC-3e/AC-3, ensuring compliance and safe operation in industrial environments.

Function

The Siemens 3RT2016-1MB41-0KT0 serves as a crucial component in industrial control systems. It is primarily used for switching and controlling three-phase electrical loads, such as motors, heating elements, and lighting systems. When a 24V DC signal is applied to the coil, it electromagnetically closes the main contacts, allowing power to flow to the connected load. When the coil is de-energized, the contacts open, interrupting the power. The integrated 1 NO auxiliary contact provides a signal to the control system, confirming the contactor’s status (e.g., “on”).

Application

• Motor control for pumps, fans, conveyors, and compressors
• Switching of heating and lighting circuits
• Integration into automated machinery and production lines
• Use in control panels and electrical distribution boards
• General industrial switching applications
