Siemens 3RT2626-1BF45 Capacitor Contactor 20 kVAr, 400V, 110V DC Coil, Size S0 Original Brand New

Overview

The Siemens 3RT2626-1BF45 is a high-performance capacitor contactor from the SIRIUS 3RT2 series, specifically designed for switching capacitive loads in AC-6b applications. This robust 3-pole contactor is ideal for use in reactive current compensation systems, managing choked or unchoked capacitors up to 20 kVAr at 400 V. The key feature of this contactor is its integrated precharging resistors, which are engaged via leading auxiliary contacts. This innovative design effectively limits the peak charging current of capacitive loads, minimizing stress on your power supply network and extending the lifespan of your equipment.

Benefit

• Extended Equipment Lifespan: By limiting the peak charging current, the 3RT2626-1BF45 reduces electrical stress on both the capacitor bank and the power supply, leading to a longer service life for your components.
• Enhanced Network Stability: The controlled switching of capacitive loads helps to prevent voltage dips and other disturbances in the power supply, contributing to a more stable and reliable electrical system.
• Reliable Performance: Built to meet rigorous IEC standards, this contactor provides dependable and consistent performance in demanding industrial environments.
• Flexible Integration: With a compact Size S0 form factor and screw terminals, the 3RT2626-1BF45 is easy to integrate into existing control panels and electrical systems.
• Convenient Auxiliary Contacts: The built-in 1 NO + 2 NC auxiliary contacts offer versatile signaling and control options for your application.
