Siemens has introduced a new fully electronic e-Starter, which utilizes semiconductor technology to enhance efficiency and reliability in industrial applications. This innovation is designed to address frequent short circuits that occur in industries such as food and beverage, intralogistics, and mechanical engineering.
The SIMATIC ET 200SP e-Starter employs silicon carbide metal-oxide semiconductor field-effect transistors (SiC MOSFETS) for ultra-fast switching. This allows the device to detect short circuits quickly, shutting off within less than 4 microseconds—approximately 1,000 times faster than conventional components. As a result, the need for replacing devices after a short circuit is eliminated, reducing downtime and warehousing costs for spare parts.
In high-efficiency motors often used in demanding environments like conveyor systems or pumps, high inrush currents can lead to unintended trips of protection devices. The phase-optimized switching and Smart Start features of the SIMATIC ET 200SP e-Starter help neutralize these currents, minimizing electrical load on the grid during start-up and reducing mechanical wear.
Andreas Matthé, CEO of Electrical Products at Siemens Smart Infrastructure, stated: “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."
The seamless integration into Siemens' Totally Integrated Automation (TIA) concept provides diagnostic functions without programming requirements and simplifies project planning through SIMATIC STEP 7 in TIA Portal. The product also boasts sustainability credentials with its minimal use of materials and energy-efficient design.
The public debut of this new starter will take place at the Smart Production Solutions (SPS) trade fair from November 12 to 14, 2024, in Nuremberg, Germany.
