🔹 Power Contactor – Siemens 3TS22110AP058K (3TS Series, 3-Pole AC Coil)
The Siemens 3TS22110AP058K is a capacitor duty power contactor from the 3TS series, designed for switching capacitor banks in power factor correction (PFC) systems. It is used in industrial electrical panels where controlled switching of capacitor loads is required to improve power factor and optimize energy efficiency.
This contactor is engineered with a pre-insertion resistor system that limits high inrush current during capacitor switching. It ensures safe operation, reduces electrical stress on capacitors, and provides long service life, making it suitable for capacitor banks, MCC panels, and industrial power distribution systems.
