Siemens 72HG34AFP Elevator Soft Starter System

Siemens 72HG34AFP Elevator Soft Starter System is a solid‑state elevator starter in Siemens’ Class 72 family, identified by catalog number 72HG34AFP and designed to control 3‑phase elevator motors. It is configured for delta‑wired installations in the high‑voltage range (460–575 VAC), making it suitable for both hydraulic and traction elevator drives. The soft starter delivers a controlled voltage ramp for start and stop, reducing inrush current and mechanical stress on the drive train while protecting connected electronics. It features adjustable overload and current‑limit ranges to tailor protection to the motor and application, a common requirement for elevator systems. As part of the 72G elevator starter lineup, it offers compatibility with other 72G components, aiding retrofit and service work by preserving familiar wiring and interfaces. This model is typically deployed in retrofit upgrades or new installations where smooth acceleration and ride comfort are priorities and a solid‑state soft‑start solution is preferred over across‑the‑line starting.
