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 extremely compact design and integrated Smart Start ensures minimal material consumption and high energy efficiency and is therefore certified with the Siemens EcoTech Profile (SEP). It’s an environmental product performance label designed to drive the sustainable transformation of industry and infrastructure. The label gives you transparency on the performance of the product across environmental relevant criteria, enabling you to make informed choices to support your sustainability goals.

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. These high currents can lead to the unwanted triggering of the protection devices. Smart Start reduces these currents, meaning the motors heat up less.

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.
