Siemens Industrial Controls – Soft Starter

With its innovative torque control system, it can be used for drives with a power output up to kW at V — respectively hp at V — in an inline circuit or up to kW at V — respectively hp at V — in an inside-delta circuit. They represent the compact and price-attractive alternative to start-delta starters. Turn off more accessible mode.

Advantages at a glance Transmission of current values Energy management: They avoid undesirable side effects such as mechanical bumps in the machine and mechanics or voltage drops in the main supply. Starting and Protecting go. Solid State Control go. Designed for simple mnaual, the functions are exceptionally easy to use.

Advantages at a Glance Soft start and soft stop Smooth starting, without steps Reduced current peaks Avoidance of line voltage fluctuations during start-up Reduced load on the power supply system Reduced mechanical load in the drive Considerable space savings and reduced wiring compared to janual starters Maintenance-free switching Ease of handling Perfectly matched with SIRIUS devices for the control cabinet.


Human Machine Interface go. Control Panel Design go.

Thanks to its innovative control method, it is not just the only 2-phase-controlled soft starter in the world for use in the power range up to kW at V — respectively hp 3rw344 V — because of its especially compact design, it ensures a space-saving, clear layout in the control cabinet.

This is because the failure of individual devices no longer influences communication. Process Instrumentation and Analytics go.

Siemens 3RW34 series

Turn on more accessible mode. And the best of it all is: Solid State Switching Devices go.

IEC Motor Control go. Process Control Systems go. Media redundancy through MRP- Thanks to the redundant design, plant and machine availability are considerably enhanced. Control Circuit Components go. Skip directly to content.

Siemens Soft Starter – Automation Technology US – Siemens

With the new Simulation Tool for Soft Starters STS we are providing a convenient way of designing soft starters using a simple, quick and easy-to-use interface. Belt slip on heater blowers or a sudden buildup of water pressure in washing installations are only two of the many problems that can occur when motors generate too much power on starting. All sizes equipped with a bypass contactor, resulting in lower power loss than conventional soft starters.


Control Products Technical Information go. The new 3RW40 soft starters in the lower power range from 5. Less heat in the cabinet: Advantages at a glance Quick, easy and user-friendly interface Complete and up-to-date Siemens motor database, including IE3 motors Update capable for new soft starters, motors or functions Quick simulation with only a few basic inputs Immediate display of starting curves and diagrams with limit values Table view of possible soft starters for the given application Text Enlarge.

It is also possible to switch straight from direct to soft start because SIRIUS 3RW30 is the only soft starter in the world that offers identical sizes in a family of devices. Motor Control Centers go. Tools Siemens Industry, Inc. The manua, start in control cabinets can be implemented in almost any application in a simple and practical way with our complete soft starter range. Entering the motor and load data will simulate the application and prompt suggestions for suitable soft starters.
