Siemens 3RT2617-1AP05 Capacitor Contactor, AC-6b 12.5 kVAr, 400V, 3-Pole Original Brand New

Overview

The Siemens 3RT2617-1AP05 is a high-performance capacitor contactor designed for reliable switching of capacitive loads (AC-6b) up to 12.5 kVAr at 400V. This specialized contactor is engineered to minimize the negative impact of high inrush currents on your power supply network. It features integrated precharging resistors that are activated via leading auxiliary contacts, which close before the main contacts to dampen the peak charging current. This makes the 3RT2617-1AP05 an ideal solution for reactive power compensation systems, as well as for switching converters.

• Easy Installation: Featuring standard screw terminals and a compact size (S00), this contactor is designed for straightforward installation and integration into existing control panels.

Function

The 3RT2617-1AP05 functions by first engaging precharging resistors through leading auxiliary contacts. This allows for a controlled, gradual charging of the capacitive load. Once the voltage is stabilized, the main contacts close, bypassing the resistors to handle the full load current. This two-stage process is crucial for safely and efficiently switching capacitors in reactive current compensation systems and other capacitive load applications.

Application

• Reactive power compensation systems
• Power factor correction
• Switching of converters and other capacitive loads
• Industrial automation and control panels

Protection & Safety Guidelines

For optimal safety and performance, it is essential to follow the recommended protection measures for all connections. Detailed information on short-circuit and overload protection for main and auxiliary circuits, as well as overvoltage protection for the control supply, is available in the provided technical documentation.
