Power Contactor, 3TS Series, 3-Pole, AC Coil, Variant AP058K - 3TS27220AP058K

🔹 Power Contactor – Siemens 3TS27220AP058K (3TS Series, 3-Pole AC Coil)

The Siemens 3TS27220AP058K is a high-capacity capacitor duty power contactor from the 3TS series, designed for switching large capacitor banks in power factor correction (PFC) systems. It is used in industrial electrical panels where controlled switching of heavy capacitor loads is required to improve power factor and overall energy efficiency.

This contactor is built with a pre-insertion resistor mechanism that limits high inrush currents during capacitor switching. It ensures safe operation, reduces electrical stress on components, and provides long service life in demanding industrial environments such as large capacitor banks, MCC panels, and power distribution systems.
