Entering the motor and load data will simulate the application and prompt suggestions for suitable soft starters. Solid State Control go.

Miniature Circuit Breakers go. 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 manul other starters Maintenance-free switching Ease of handling Perfectly matched with SIRIUS devices for the control cabinet.

The new 3RW40 soft starters in the lower power range from 5. Control Panel Design go. Turn on more accessible mode. Solid State Switching Devices go.

All sizes equipped with a bypass contactor, resulting in lower power loss than conventional soft starters. They represent the compact and price-attractive alternative to start-delta starters.


Process Control Systems go. IEC Motor Control go. 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.

Turn off more accessible mode. Advantages at a glance Transmission of current values Energy management: The soft start in control cabinets can be implemented in almost any application in a simple and practical way with our complete soft starter range.

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.

This is because the failure of individual devices no longer influences communication.

Siemens 3RW34 series

Starting and Protecting go. Process Instrumentation and Analytics go. 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. 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 at V — because of its especially compact design, it ensures a space-saving, clear layout in the control cabinet.

Tools Siemens Industry, Inc. Search Search term s Search. With the new Simulation Tool for Soft Starters Mnaual we are providing a convenient way of designing soft starters using a simple, quick and easy-to-use interface. Control Circuit Components go.

And the best of it all is: Designed for simple handling, the functions are exceptionally easy to use. Media redundancy through MRP- Thanks to the redundant design, plant and machine availability are considerably enhanced. Less heat in the cabinet: They avoid undesirable side effects such as mechanical bumps in the machine and mechanics or voltage drops in the main supply.
