How Siemens 3MT7 Contactor Works

Capacitor banks play a crucial role in improving power factor in low voltage systems. However, during capacitor switching, high inrush currents occur due to network inductance, transformer power, and harmonic distortions. Standard contactors may not withstand these peak currents, leading to contact welding.

Siemens 3MT7 capacitor duty contactors are designed with a specialized damping resistor mechanism that limits peak inrush currents, ensuring reliable and long-lasting operation. The front-mounted auxiliary contact block activates damping resistors before main contacts close, ensuring smooth and safe capacitor switching.
