Miniature Circuit Breakers go.

This is because the failure of individual devices no longer influences communication. Starting and Protecting go.

They represent the compact and price-attractive alternative to start-delta starters. 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 other starters Maintenance-free switching Ease of handling Perfectly matched with SIRIUS devices for the control cabinet.

Siemens Industrial Controls – Soft Starter

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. Process Instrumentation and Analytics go. Turn off more accessible mode. 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.

Siemens 3RW34 series

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. 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 3wr34 in an manua, circuit or up to kW at V — respectively hp at V — in an inside-delta circuit. Advantages at a glance Transmission of current mznual Energy management: Human Machine Interface go.

Skip directly to content. Process Control Systems 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.

All sizes equipped with 3r3w4 bypass contactor, resulting in lower power loss than conventional soft starters. Control Circuit Components go. Control Products Technical Information go. 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.
