Siemens 72LG34AFA

The Siemens 72LG34AFA is an elevator starter designed as an AC semiconductor motor soft starter, well-suited for controlling three-phase motors. This soft start unit helps manage the motor’s acceleration smoothly, reducing mechanical stress and electrical peak loads during startup. It supports hydraulic elevator systems at voltage ratings of 200, 230, or 460 volts and operates effectively across both 50 and 60 Hz frequencies. For traction elevator applications, it also accommodates the same voltage range. In terms of power handling, the starter is rated for hydraulic elevator motors up to 25, 30, or 60 horsepower (depending on voltage) and traction motors up to 20, 25, or 50 horsepower. It provides up to 80 amps in delta configuration for hydraulic systems, ensuring reliable motor protection and soft starting performance. Products like this Siemens soft starter are available through BSP Automation, providing robust solutions for elevator motor control needs.
