Siemens SIRIUS 3RT2626-1AK65 Capacitor Contactor, AC-6b 20 kVAr / 400V, 3-pole, 110V AC / 120V AC Coil, 1 NO + 2 NC Aux Contacts, Size S0 Original Brand New

Overview

The Siemens SIRIUS 3RT2626-1AK65 is a high-performance capacitor contactor specifically engineered for switching capacitive loads in reactive current compensation systems. This specialized version of the SIRIUS 3RT2 series is designed to handle AC-6b applications up to 20 kVAr at 400 V. Its unique design, featuring leading auxiliary contacts and precharging resistors, effectively limits peak charging currents, minimizing stress on the power supply network and extending the lifespan of your equipment.

This 3-pole contactor is equipped with a dual-frequency coil, operating at 110 V AC (50 Hz) or 120 V AC (60 Hz). It comes with two freely accessible auxiliary contacts (1 NO + 2 NC) for seamless integration into control circuits and features reliable screw terminals for easy and secure wiring. The compact Size S0 makes it an ideal choice for space-constrained control panels.

Benefit

• Optimized for Capacitive Loads: Specifically designed for AC-6b switching, ensuring reliable and safe operation with capacitors.
• Extended Equipment Life: Precharging resistors limit high inrush currents, reducing wear and tear on capacitors and the power grid.
• Improved Power Quality: Minimizes negative impacts on the power supply network caused by high current peaks.
• Versatile Control: Dual-frequency coil (110 V AC / 120 V AC) and multiple auxiliary contacts (1 NO + 2 NC) offer flexible integration into various control systems.
• Robust and Reliable: Built to Siemens' high-quality standards, ensuring long-term performance and durability.
• Compact Design: The Size S0 form factor allows for efficient use of space in control cabinets.

Function

• Capacitor Switching (AC-6b): Switches capacitive loads in applications such as power factor correction and reactive current compensation.
• Inrush Current Limitation: Utilizes leading auxiliary contacts and integrated precharging resistors to dampen the high inrush currents typical of capacitive loads.
• Converter Switching: Suitable for switching converters in various industrial applications.
