Siemens 3RT2617-1BF43 Capacitor Contactor, S00, 12.5 kVAr, 400V, 110V DC, 1 NO + 1 NC Auxiliary Contact Original Brand New

Overview

The Siemens 3RT2617-1BF43 is a highly specialized capacitor contactor from the SIRIUS 3RT26 series, engineered for the demanding task of switching capacitive loads (AC-6b). This robust 3-pole device is designed to handle up to 12.5 kVAr at 400V, making it an essential component in reactive power compensation systems and for switching converters. Its key feature is the integration of precharging resistors, which are engaged via leading auxiliary contacts. This innovative design effectively limits the peak charging current, thereby minimizing stress on the power supply network and extending the lifespan of both the contactor and the connected capacitors.

Benefit

• Extended Equipment Life: By minimizing peak charging currents, the 3RT2617-1BF43 reduces electrical stress on capacitors and other components in the system.
• Improved Power Quality: Limiting inrush current prevents voltage sags and disturbances on the power grid, contributing to a more stable electrical supply.
• Reliable Performance: Built to stringent IEC standards (IEC 60947, IEC 60831), this contactor ensures safe and reliable operation in industrial environments.
• Flexible Control: The 110 V DC coil offers a reliable control option, and the included 1 NO + 1 NC auxiliary contacts provide versatile feedback and control possibilities.
• Ease of Installation: Screw terminals simplify wiring, and the compact Size S00 footprint allows for efficient use of panel space.

Features & Function

• Application: Specifically designed for switching capacitive loads in accordance with the AC-6b utilization category.
• Precharging Resistors: These resistors are switched on via leading auxiliary contacts to effectively limit the inrush current during the switching process.
• Auxiliary Contacts: The contactor includes 1 normally open (NO) and 1 normally closed (NC) auxiliary contact, which can be used for signaling the contactor’s status or for interlock circuits.
• Control Voltage: The device is controlled by a 110 V DC supply voltage, ensuring reliable switching.
• Terminal Type: Features secure screw terminals for robust and straightforward wiring.
• Standards Compliance: Conforms to international standards including IEC 60947-1, IEC 60947-4-1, IEC 60947-5-1, IEC 60831-1, and IEC 61921.
• Modular Design: As a member of the SIRIUS family, it can be easily integrated with other Siemens components and expanded with additional auxiliary switches or surge suppressors.
