Siemens 3RT2625-1AB05 SIRIUS Capacitor Contactor, 16.7 kVAr, 400V, 24V AC, Size S0 Original Brand New

Overview

The Siemens 3RT2625-1AB05 is a high-performance capacitor contactor from the SIRIUS family, specifically engineered for switching capacitive loads in reactive power compensation systems. This specialized contactor is designed to handle AC-6b loads up to 16.7 kVAr at 400 V, ensuring reliable and efficient operation. Its key feature is the inclusion of leading auxiliary contacts that engage precharging resistors.

This innovative design effectively limits inrush current peaks, a common issue when switching capacitors, thereby minimizing negative impacts on the power grid and extending the lifespan of both the contactor and the connected capacitors. The 3RT2625-1AB05 is a 3-pole contactor with a 24V AC, 50 Hz control voltage, and comes equipped with 1 NO + 2 NC auxiliary contacts and secure screw terminals.

Features & Benefits

• Optimized for Capacitive Loads: The built-in precharging resistors, activated by leading auxiliary contacts, dramatically reduce inrush current peaks. This protects the power supply network and the connected equipment from electrical stress.
• High Performance: Capable of switching capacitive loads up to 16.7 kVAr at 400 V (AC-6b), making it ideal for reactive power compensation systems.
• Robust and Reliable: Built to Siemens’ rigorous quality standards, ensuring long-term reliability and performance in demanding industrial environments.
• Versatile Applications: Suitable for switching both choked and unchoked capacitors in reactive current compensation systems, as well as for switching converters.
• Comprehensive Protection: The product description provides detailed guidance for protecting all connections (main, auxiliary, and control) against short circuits, overloads, and overvoltage, allowing for safe and standards-compliant installation.
• Expandable Functionality: The basic unit is equipped with integrated auxiliary contacts, with the possibility to add more lateral auxiliary switches for enhanced control and monitoring capabilities.
• Standards Compliant: Conforms to key international standards including IEC 60947-1, IEC 60947-4-1, IEC 60947-5-1, IEC 60831-1, and IEC 61921, guaranteeing safety and compatibility.
