Always ahead of the peak

An innovative combination of semiconductor components, sensors, a microcontroller, and intelligent algorithms enables ultra-fast wear-free switching. It reacts up to 1,000 times faster to current peaks, reducing the energy in the event of a short circuit by up to 99.5%. At the same time, high inrush currents are efficiently managed when starting high-efficiency motors.

The benefits are clear: less and shorter downtime, an immediate restart after fault clearance, and no false tripping due to high inrush currents. Semiconductor technology also reduces the effort required for short-circuit and selectivity planning and mechanical wear thanks to electronic switching. It also reduces the need for service interventions and inventory requirements and prevents short-circuit damage to equipment.

The right choice for the environment

The SIMATIC ET 200SP e-Starter protects not only your applications, but also valuable resources thanks to the durability of its innovative semiconductor technology. In addition, its compact design and integrated Smart Start ensures minimal material consumption and high energy efficiency and is therefore certified with the Siemens EcoTech label.

This certification evaluates products based on transparent, standardized criteria throughout their entire lifecycle, taking into account factors such as material usage, energy efficiency, repairability, and recyclability. It provides clear, transparent information on the SIMATIC ET 200SP e‑Starter’s environmental performance, enabling you to use it confidently as a sustainable solution in your facility.

Smart Start protects motors and applications

The integrated Smart Start feature neutralizes inrush currents and reduces starting currents. This reduces the torque when starting motors. High starting currents particularly occur in highly efficient motors, such as those in energy efficiency classes IE3 and IE4.

This significantly reduces mechanical load and prevents damage to gears, which is particularly relevant in applications with high switching frequencies. In short, Smart Start protects highly efficient motors and sensitive applications, reduces the need for mechanical maintenance, and prevents unwanted trips from other protection devices during start-up.

Easily implement safety applications

The e-Starter comes with a Standard Submodule that enables a safe motor shutdown thanks to its integrated Safe Torque Off (STO) function. Accordingly, it meets the highest safety standards according to IEC 61508 / 62061 (SIL 3) and ISO 13849 (Performance Level e, Category 4). This makes the e‑Starter ideal for safety-related applications that require the highest level of personnel and equipment protection.

Advanced applications for demanding use cases

The new Standard Submodule for the SIMATIC ET 200SP e‑Starter expands the range of applications to include highly demanding industrial applications that require a safety-related shutdown up to SIL 3, PL e, Category 4. A reliable, fail-safe shutdown of motors is essential for protecting people and preventing plant damage. The e‑Starter complies with all relevant standards required for this purpose, including IEC 61508, IEC 62061, and ISO 13849‑1. With the Safe Torque Off (STO) safety function integrated into the Standard Submodule, the motor is immediately shut down in an emergency and remains safely switched off until it is deliberately restarted in a controlled manner.

Protection of motors in potentially explosive areas

In addition, the e-Starter with the new Standard Submodule is approved for the operation and protection of motors in hazardous areas of Zones 1/21 and complies with the requirements of the ATEX Directive 2014/34/EU as well as the international IECEx certification scheme. This makes it ideally suited for use in explosive atmospheres and ensures safe and reliable protection in such environments.

Greater transparency through enhanced condition monitoring

The new Standard Submodule also provides extended condition monitoring functions. Monitoring of active power for detecting load variations enables analysis of energy consumption. Recording the switching frequency supports the evaluation of thermal stress. These functions increase transparency during operation and help to plan maintenance activities in a targeted manner, reduce unplanned downtime, and sustainably increase plant availability.
