Motor Starters

An integrated solution that combines a contactor and overload protection into a single unit to safely start, stop, and protect electric motors.

Siemens | SIRIUS 3RW motor starters

SIRIUS soft starters are the best solution when direct-on-line or star/delta starting are not suitable for three-phase motors, because mechanical impacts in the machine or voltage dips in the power supply system can often cause problems.

SIRIUS 3RW52

Model Number: 3RW52263AC05

5.5-560kW. All-rounder, it covers all drive types.

Key Technical Specifications:

  • A wide range of communications interfaces (PROFINET, PROFIBUS, EtherNet/IP, Modbus)

  • Three-phase controlled for optimal motor start.

  • Integration in the process control system PCS 7 V9.0 SP2 with the 3RW5 block library.

SIRIUS 3RW55 (failsafe)

Model Number: 3RW40371BB04

Failsafe soft starters with integrated Safe Torque Off (STO) functionality, and safety-related applications. 5.5-1200kW

Key Technical Specifications:

  • Integration in the process control system PCS 7 V9.0 SP2 with the 3RW5 block library

  • Direct communication into cloud-based solutions via OPC UA

  • Integrated, safety-related shutdown for SIL 1/PL c and SIL 3/PL e (with STO)

Schneider Electric | TeSys™ U-Line & Deca

Schneider’s TeSys U is widely considered the world’s most “intelligent” starter. It is an all-in-one “Starter-Controller” that integrates the functions of a circuit breaker, contactor, and overload into a single 45mm-wide block. It is the primary choice for space-constrained cabinets where “Total Coordination” is required.

TeSys U (LUB)

Model Number: LUB12

Modular plug-in design; wide-range control units (0.15 to 32A); integrated Modbus/AS-i options.

Key Technical Specifications:

  • The protection parameters (current range and trip class) are determined by a small “Control Unit” that snaps into the power base without tools, allowing the motor to be defined at the last minute on-site.

  • Saves up to 57% of cabinet space compared to traditional three-component starters, as the reversing logic is built into the same 45mm width.

TeSys Deca (LC1)

Model Number: LUCB05BL

The world’s most popular contactor/starter line; up to 150A; “EverLink” power terminals.

Key Technical Specifications:

  • Uses a spring-loaded terminal block that compensates for the “creep” of copper wires, ensuring the power connections never become loose or overheat over time.

  • Features a specific low-consumption 24V DC coil that can be driven directly by a PLC output without the need for an intermediate “coupling” relay.
