Siemens 3RT2627-1BB45 Capacitor Contactor, AC-6b 25 kVAr, 24V DC, S0 Size, Screw Terminal Original Brand New

Overview

The Siemens 3RT2627-1BB45 is a specialized capacitor contactor designed for switching capacitive loads in applications such as reactive current compensation systems. As part of the SIRIUS 3RT26 series, this contactor is engineered to handle AC-6b loads up to 25 kVAr at 400V. Its unique design incorporates leading auxiliary contacts that activate precharging resistors, effectively limiting the inrush current that can damage components and disrupt the power supply network. With a compact Size S0 frame, a 24V DC control coil, and robust screw terminals, this device is a reliable and efficient solution for controlling capacitor banks. It is compliant with international standards, including IEC 60947 series, ensuring safety and performance.

Key Benefit

• Extended Equipment Lifespan: By limiting peak charging currents, the 3RT2627-1BB45 protects capacitors and other system components from stress, extending their operational life.
• Improved Power Quality: Minimizes voltage sags and disturbances on the power supply network caused by high inrush currents during switching.
• Versatile Application: Ideal for switching both choked and unchoked capacitors in reactive power compensation systems and for controlling converters.
• Reliable Performance: Built to comply with rigorous international standards (IEC 60947, IEC 60831), ensuring high reliability and safety.
• Convenient Installation: Features user-friendly screw terminals and a compact Size S0 design for easy integration into control panels.

Key Function

• Capacitive Load Switching (AC-6b): Designed specifically to handle the unique challenges of switching capacitive loads, preventing current peaks.
• Precharging Resistors: Utilizes built-in precharging resistors, activated by leading auxiliary contacts, to absorb the initial high inrush current.
• 3-Pole Switching: Controls all three phases of a three-phase capacitive load.
• 24V DC Control: Operates with a standard 24V DC control voltage, making it compatible with a wide range of industrial control systems.
• Integrated Auxiliary Contacts: The basic unit includes 1 normally open (NO) and 2 normally closed (NC) auxiliary contacts for feedback and interlocking purposes.

Important Safety & Installation Information

• All connections must be protected against short circuits and overloads. Refer to the product data sheet and configuration manuals for detailed protection requirements.
• The use of surge suppressors for the control supply coil will increase the contactor’s break times.
• This product can be expanded with additional lateral auxiliary switches; please adhere to the permissible configurations outlined in the equipment manual.
