Siemens Soft Starter, 24V AC/DC Control Voltage, 72A Current Rating - SIRIUS Series - 3RW4038-1BB04


Gently ease your three-phase induction motor into operation with this soft starter from Siemens. It controls the supply of voltage and current during start-up, so prevents surges that could damage your motor. The device also supports a smooth wind down by gradually reducing the generated torque. When it's up and running, the thyristors in the soft starter are bridged by bypass contacts, which minimises the generation of waste heat and helps to keep everything running cool. Adjustable current limitation means you can choose the ratings that best suit your needs. You'll find modules like this used with motor-powered industrial equipment, such as conveyor belts and compressors.

Features & Benefits


• Choose screw or snap-on mounting to suit your setup

• Compact dimensions of 160 (H) x 55 (W) x 170mm (D) maximise board packing efficiency

• Screw terminals hold wires securely, so reduce the need for regular re-tightening

• Wide operating temperature range between -25°C and +60°C for compatibility with harsh industrial environments

Can I use this soft starter with a piston pump?


Yes, this soft starter is ideal for firing up a piston pump as it ensures there are no pressure surges that could decrease the lifespan of your pipe system.
