Siemens 3RK1301 0BB10 1AA2 E07 Modular Starter

Siemen’s 3RK1301-0BB10-0AA2 E07 Modular Starter is a DS1-X direct-starter module in the ET 200S motor-starter family, designed for compact, modular motor starting within Siemens’ ET 200S distributed I/O architecture. It provides direct starting of three-phase motors and includes high-feature electronic overload protection, aligning with the DS1-X direct-starter concept used for brake-control and motor-start tasks in ET 200S configurations. This module is intended to mount on the ET 200S backplane and can be paired with the IM 151 interface module (for example 6ES7151-1AA00-8AA0) to enable distributed control of motor-start sequences within an automation rack. The 3RK1301 family comprises several variants with differing current ranges and protection features, and the 0BB10 variants are documented as direct-starter options with high-feature protection tailored for integrated motor-start applications in ET 200S systems. When used as part of an ET 200S starter assembly, these modules integrate into Siemens’ automation ecosystem, offering a space-efficient solution for motor control in applications such as conveyors, pumps, and packaging lines where brake-control or motor-start sequencing is required in a modular, field-bbus-enabled setup.
