Siemens introduces SIMOVAC arc-resistant and non-arc-resistant medium-voltage controllers

Wendell, NC | Feb 14, 2013

Siemens Infrastructure & Cities Low and Medium Voltage division today announced the introduction of its SIMOVAC medium-voltage motor controller. The new two-high controller is designed to provide users with a product that offers increased safety, ease of use, cost improvement, increased reliability, innovative features and greater flexibility. It is designed for industrial, commercial and utility customers in the U.S. and wherever NEMA and ANSI standards are required.


“Siemens has been manufacturing medium-voltage controllers for more than 50 years,” says John Karczmarczyk, vice president of Medium Voltage and Systems, Siemens Infrastructure & Cities. “We have listened to the needs of our customers and tapped the experience and knowledge of our internal experts to develop this new controller product.”


The SIMOVAC controller is available in arc-resistant and non-arc-resistant designs to provide superior control and protection for large motors, transformers and capacitor bank applications. The compact and rugged enclosure design of SIMOVAC is tested to the latest UL and CSA standards and the arc-resistant version has been successfully tested to ANSI/IEEE C37.20.7.


"Customers will find the SIMOVAC controllers very easy to specify, install, operate and maintain," says Jarvis Simmons, product lifecycle manager, Siemens Infrastructure & Cities. “The arc-resistant transition to the Siemens GM-SG-AR metal-clad switchgear provides for compact integrated controller and switchgear lineups.”
