Overview
The Siemens 3RT2626-1AC25 is a high-performance capacitor contactor specifically engineered for switching capacitive loads in reactive current compensation systems. This specialized device is a part of the SIRIUS 3RT2 product family, designed to handle AC-6b loads up to 20 kVAr at 400V. The unique design features integrated precharging resistors, which are engaged via leading auxiliary contacts.
This mechanism effectively limits the inrush current, minimizing stress on the power supply network and extending the lifespan of your equipment. With a compact Size S0 form factor, a 24V AC control voltage, and robust screw terminals, the 3RT2626-1AC25 offers a reliable and efficient solution for controlling capacitors in both choked and unchoked applications.
