Siemens 3RT2016-2KB41 SIRIUS 3RT2 Power Contactor, 9A, 4kW, 24V DC, S00 Frame Original Brand New

Overview

The Siemens 3RT2016-2KB41 is a high-performance power contactor from the SIRIUS 3RT2 series, designed for demanding industrial applications. This compact and reliable device is engineered for switching and controlling motors and other electrical loads up to 4 kW at 400 V.

With a nominal current rating of 9 A (AC-3e/AC-3), it is a versatile solution for a wide range of control tasks. The integrated suppressor diode protects against voltage spikes, ensuring the longevity and reliability of your system’s PLC outputs. Its spring-loaded terminals offer fast, secure, and vibration-resistant connections, making installation and maintenance highly efficient.

Features & Benefit

• Optimized for PLC Outputs: The integrated suppressor diode and low power consumption make this contactor perfectly suited for direct control by sensitive PLC outputs, reducing the need for additional interface relays.
• High Reliability: The integrated suppressor diode effectively dampens voltage surges, protecting the contactor coil and connected electronic components from damage.
• Space-Saving Design: The compact S00 frame size allows for high-density mounting in control cabinets, saving valuable space.
• Effortless Installation: Spring-loaded terminals provide a quick and secure connection without the need for tools, offering excellent resistance to vibration and temperature fluctuations.
• Durable Performance: Built to Siemens’ high standards, this contactor offers a long electrical and mechanical lifespan, ensuring continuous and reliable operation in industrial environments.
• Safety and Compliance: Meets modern standards for AC-3e/AC-3 operation, ensuring safe and efficient motor control.
• Clear Status Indication: The integrated 1 NO auxiliary contact provides immediate feedback on the contactor’s switching status, essential for monitoring and safety circuits.

Functionality

The Siemens 3RT2016-2KB41 power contactor is a three-pole device used for switching power circuits. When the 24 V DC control voltage is applied to the coil (within the 0.7 to 1.25*Uc range), the main contacts close, allowing power to flow to the connected load.

Simultaneously, the integrated 1 NO (Normally Open) auxiliary contact changes state, providing a signal that the main circuit is closed. The integrated suppressor diode protects the coil and the controlling PLC from reverse voltage spikes that occur when the coil is de-energized. The spring-loaded terminals ensure a reliable, gas-tight connection, preventing performance degradation over time.
