Siemens 3RW4037 1BB14 Sirius Soft Starter

Siemens Sirius 3RW4037 1BB14 

Siemens 3RW4037 1BB14 is a compact starter solution for standard machine applications, with two-phase control enabling three-phase asynchronous motor starting. The two-phase control keeps the current down to minimum values in all three of the motor’s phases during the whole starting time. 3RW soft starts are available in power ratings from 5.5 to 250 kW at 400V and control voltages of 24V AC/DC or 110…230V AC/DC.

Siemens 3RW40 soft starts have a small modular design that has a clearly arranged layout of the control panel and compact screw- or spring-type mounting that saves space in the control cabinet. Units feature box terminals as well as cable lug and busbar connections, plus auxiliary terminals and link module for a motor starter protector. 3RW40 soft starts also fall into the Siemens Sirius size range with soft starts available in sizes S00, S0, S2, S3, S6 and S12. Siemens 3RW40 in soft starter sizes S0 to S12 are also suitable for the starting of explosion-proof motors that require “increased safety” protection EEx e.
