ET 200SP motor starter

ET 200SP is a scalable, highly flexible and modular I/O system with IP20 degree of protection. As I/O modules, the ET 200SP motor starters are an integral part of this I/O system. They are switching and protection devices for single- and three-phase loads and are available as direct or reversing starters

Motor starter, BaseUnit and 3DI/LC control module

3RK1308 motor starter in the ET 200SP I/O system

Basic functionality

All versions of the ET 200SP motor starters have the following functionality:

• Fully pre-wired motor starters for switching and protecting any AC loads up to 4 kW at 400 V AC and 500 V AC
• With self-assembling 32 A power bus, i.e. the load voltage is only fed in once for a group of motor starters
• All control supply voltages connected only once, i.e. when modules are added they are automatically connected to the next module
• Hot swapping is permissible
• Digital bs can be used optionally via a 3DI/LC module
• Control of the motor starter from the control system and extensive diagnostics status via the cyclic process image
• Diagnostics capability for active monitoring of the switching and protection functions
• The signal states in the process image of the motor starter provide inbation about protective devices (short circuit or overload), the switching states of the motor starter, and system faults.

Article No. scheme

¹⁾ for standard motors: Single- or three-phase asynchronous motors, single-phase AC motors, single-phase asynchronous motors, at 400 V AC, the actual startup characteristics of the motor as well as its rated data are important factors here.

The Article No. scheme shows an overview of product versions for better understanding of the logic behind the article numbers. For your order please use the article numbers quoted in the selection and ordering data.

BaseUnits for motor starters

BaseUnits are components for accommodating the ET 200SP I/O modules. The self-assembling voltage buses integrated into the BaseUnits reduce wiring outlay to the single infeed (both of auxiliary and load voltage).

All modules following on the right are automatically supplied upon plugging the BaseUnits together, if BaseUnits are inserted with routing. The rugged design and keyed connection technology enables use in harsh industrial conditions.

The BaseUnits are available with various infeeds for the motor starters.

3DI/LC control module

This is a digital b module with three bs for local motor starter functions such as "manual local control", implementation of fast bs or "end b disconnection".

For a list of all the functions permitted by the 3DI/LC module, see Manual "ET 200SP Motor Starters", "Function overview" section https://support.industry.siemens.com/cs/ww/en/view/109479973 .

The module is plugged into the front of the motor starter from which it is supplied with a DC 24 V operating voltage.

Product advantages

The ET 200SP motor starters offer a number of benefits:

• Fully integrated in the ET 200SP system (including TIA Selection Tool and TIA Portal)
• Simple, integrated current value transmission
• Extensive beterization by means of TIA Portal
• Increase of plant availability through fast replacement of units (easy mounting and plug-in technology)
• Longer service life and reduced heat losses thanks to hybrid technology
• Less space required in the control cabinet (20 to 80%) as a result of greater functional density (direct-on-line and reversing starters in same b)
• Extensive diagnostics and inbation for preventive maintenance
• Parameterizable bs via 3DI/LC control module
• Less wiring and testing required as a result of integrating several functions into a single device
• Lower overheads for stockkeeping and configuration as a result of the wide setting range of the electronic overload release (up to 1:3)
• Technology-reduced inherent power loss as speed-controlled drive systems, enabling also lower cooling effort required (and enabling a more compact design)

The ET 200SP motor starters can be used with highly energy-efficient IE3/IE4 motors.

Standards and approvals

• IEC/EN 60947-4-2
• UL 508
• CCC approval for China

The ET 200SP motor starters are suitable for the following applications:

• Switching and monitoring of
  • 3-phase motors with overload and short-circuit protection (e.g. 400 V asynchronous motors for secondary drives in conveyor systems)
  • 1-phase motors with overload and short-circuit protection (e.g. 250 V motors for pump applications)
  • Resistive loads by means of current value and diagnosis via the maintenance function (e.g. for gas discharge lamps and heaters)
• Plant monitoring and energy management in conveyor systems 
  By means of the phase asymmetry and zero current detection during current measurement, for example, drive belt monitoring and blocking monitoring are possible.
• Track switching and lifting table control in conveyor systems 
  Track switches can be implemented using the quick stop function and lifting table controls by means of the "immediate end b disconnection" function without any laborious programming.
• Safe isolation of the drive from main power supply 
  The isolating function according to IEC 60947-1 offers protection against inadvertent activation during plant maintenance.
