Capacitor SW. Contactor, AC-6B 20 kVAR / 415 V-3TS1411-0AP05-8K

Product Description

Capacitor Switching Contactor, AC-6b, 20 kVAr / 415 V – 3TS1411-0AP05-8K

The Siemens 3TS1411-0AP05-8K is a dedicated capacitor duty switching contactor designed for reliable switching of power factor correction (PFC) capacitor banks in low-voltage electrical systems. It is engineered for AC-6b utilization category, ensuring safe handling of high inrush currents generated during capacitor switching operations.

This model is rated for 20 kVAr at 415 V AC (3-phase, 50 Hz) and is built with an advanced pre-charge and damping resistor mechanism, which significantly reduces switching transients and protects both the capacitor bank and contactor contacts. The integrated early-make auxiliary contact system ensures capacitors are pre-charged before main contact closure, improving system reliability and extending equipment life.

The 3TS1411-0AP05-8K is widely used in automatic power factor correction panels, industrial electrical distribution systems, commercial buildings, and capacitor bank control systems, where stable reactive power management is required.
