Siemens introduces electronic motor starter with fast-response short-circuit protection

Siemens unveils ultra-fast motor starter for improved fire safety in industrial applications

Siemens Smart Infrastructure has introduced the SIMATIC ET 200SP e-Starter, a fully electronic motor starter designed to improve industrial safety by delivering ultra-fast short-circuit protection.

As reported by Siemens, the device utilises advanced semiconductor technology, offering response times 1,000 times faster than conventional motor starters, making it particularly relevant to fire safety in demanding industrial applications such as food and beverage processing, intralogistics, and mechanical engineering.

This starter offers critical motor protection while integrating seamlessly into Siemens’ Totally Integrated Automation (TIA) platform.

The SIMATIC ET 200SP e-Starter employs silicon carbide metal-oxide semiconductor field-effect transistors (SiC MOSFETS), allowing it to handle short circuits with minimal wear.

The device shuts down within less than 4 microseconds in response to a short circuit, reducing the risk of overheating and potential fire hazards in industrial environments.

This rapid response minimises the need for component replacement, reducing maintenance demands and potential costs.

Enhanced protection for high-efficiency motors

Industries that rely on high-efficiency motors, such as those in the IE3 and IE4 energy classes, benefit from the e-Starter’s short-circuit protection capabilities, which counter the risk of short circuits and overheating—a frequent concern in fire safety.

These motors often produce high inrush currents at startup, which can cause traditional protection devices to trip unintentionally.

Siemens addresses this issue with the e-Starter’s phase-optimised switching and Smart Start feature, which neutralises these inrush currents.

This feature not only reduces the electrical load on the system but also protects the starter from damage, further minimising the fire hazards associated with high-current spikes.

Diagnostic and automation integration features

The SIMATIC ET 200SP e-Starter is compatible with Siemens’ Totally Integrated Automation (TIA) platform, allowing manufacturers and integrators to benefit from integrated diagnostic capabilities.

This functionality provides real-time system diagnostics, helping engineers to detect and address potential issues before they escalate into safety risks.

Andreas Matthé, CEO of Electrical Products at Siemens Smart Infrastructure, said: “Our fully electronic e-Starter is a real innovation that offers many benefits over traditional electromechanical or hybrid motor starters.

“We developed it in close consultation with potential users. That is why it responds to their challenges exactly as needed.

“It makes demanding motors and applications more available, durable, and user-friendly than ever before.”

Sustainable and energy-efficient design

In line with Siemens’ commitment to sustainability, the e-Starter is designed for energy efficiency and reduced material usage, earning it the Siemens EcoTech label.

The starter’s wear-free switching extends its operational life, while its use of recycled materials and low energy consumption contribute to a more sustainable footprint.

These qualities offer environmental benefits while ensuring long-lasting protection against electrical hazards, further enhancing fire safety for high-demand industrial applications.

The SIMATIC ET 200SP e-Starter will be presented at the Smart Production Solutions (SPS) trade fair in Nuremberg, Germany, from November 12 to 14, 2024.

Siemens aims to showcase the benefits of its integrated and sustainable design for industrial users worldwide.
