Compact Motor Starter employs hybrid technology.
Press Release Summary:
December 3, 2012 - Occupying minimal control cabinet space with its 22.5 mm width, Sirius 3RM1 is designed as direct-on-line starter and reversing starter with integrated overload protection for switching up to 3 kW motors. Semiconductor components are responsible for connection and disconnection operations, while relay system is used during operation. This combination extends service life and reduces maintenance. Available infeed system facilitates accelerated implementation of assemblies.

Siemens Expands Sirius Portfolio with Particularly Compact Motor Starter
Press release date: November 19, 2012
.At just 22.5 mm wide, the Sirius 3RM1 motor starter from Siemens is extremely compact and has been designed as both a direct-on-line starter and a reversing starter for switching small motors with a rating of up to 3 kW.
.The Siemens Industry Automation Division has added the particularly compact Sirius 3RM1 motor starter to its switching technology portfolio. The module has been designed as both a direct-on-line starter and a reversing starter with integrated overload protection for smaller motors with a rating of up to 3 kW, used, for example, for fans, pumps and lifting gear as well as in machine tools. At just 22.5 mm wide, the Sirius 3RM1 requires very little space in the control cabinet. The motor starter therefore meets the requirement in modern plant and machinery construction for space-saving components.
Besides its narrow profile, the Sirius 3RM1 is also characterized by economical hybrid technology that combines the benefits of semiconductor and relay systems in one device: the low-wear semiconductor components are responsible for connection and disconnection operations while an energy-efficient relay system is used during operation. This extends the motor starter's service life and reduces maintenance demands. Siemens also offers a special infeed system for the new motor starter which permits fast and simple implementation of assemblies. As the main circuit is centrally connected to the infeed system, there is no need for separate wiring of the individual motor starters. The assembly with the infeed system is particularly suitable for conveyor systems in which a large number of motors are used on one conveyor belt. When maintenance is required, the individual motor starters from an existing assembly can be removed from the group with little effort thanks to the infeed system. Moreover, the motor starters can also be simply slotted in in the main circuit using a device connector, so there is no need for extensive manual power supply wiring between the motor starters in the assembly. Wiring errors cannot therefore occur and commissioning of the motor starters is speeded up.
