Siemens 3RT2617-1AB03 Capacitor Contactor: 12.5 kVAr, 400V, 3-Pole, 24V AC Control Original Brand New

Overview

The Siemens 3RT2617-1AB03 is a specialized capacitor contactor from the SIRIUS 3RT26 series, engineered for the reliable switching of capacitive loads. Specifically designed for AC-6b applications, this 3-pole contactor is rated for 12.5 kVAr at 400 V.

It features a 24 V AC control voltage (50/60 Hz) and comes with a 1 Normally Open (NO) and 1 Normally Closed (NC) auxiliary contact configuration, all housed in a compact size S00 frame with secure screw terminals.

A key feature of the 3RT26 series is the integrated precharging resistors, which are engaged via leading auxiliary contacts. These resistors effectively limit the inrush current spikes that are characteristic of capacitive loads, protecting the power supply network and extending the lifespan of the equipment.

The 3RT2617-1AB03 is an ideal component for reactive current compensation systems, switching choked or unchoked capacitors, and is also suitable for converter applications.

Key Features & Benefits

• Optimized for Capacitive Loads: Specifically designed for AC-6b operation, ensuring safe and reliable switching of capacitors up to 12.5 kVAr.
• Inrush Current Limitation: Integrated precharging resistors minimize peak charging currents, protecting the power network and connected devices.
• Compact & Efficient Design: Size S00 form factor allows for space-saving installation in control panels.
• Versatile Auxiliary Contacts: Includes 1 NO + 1 NC auxiliary contacts for flexible integration into control circuits and monitoring systems.
• Secure & Reliable Connections: Screw terminals provide a robust and easy-to-wire connection for both main and auxiliary circuits.
• Broad Application: Suitable for use in reactive power compensation systems, as well as for switching converters.
• Compliance with Global Standards: Manufactured in accordance with international standards including IEC 60947-1, IEC 60947-4-1, IEC 60831-1, and others, ensuring high quality and safety.

Additional Information

• Short-Circuit and Overload Protection: It is crucial to use appropriate protection devices for all connections (main, auxiliary, and control). For detailed guidance, consult the technical product data sheet or the Digital Configuration Manual for load feeders.
• Overvoltage Protection: Overvoltage suppressors (RC elements, varistors, etc.) can be retrofitted to the coil circuit for damping opening surges. These must be ordered separately.
• Auxiliary Contact Expansion: The 3RT261 basic unit includes freely accessible auxiliary contacts. For additional needs, refer to the product documentation for permissible lateral auxiliary switch configurations.
