EC: tiastar Arc-resistant motor control center

Power – Motor control center: Siemens’ arc-resistant tiastar Motor Control Center significantly reduces risk for workers entering areas with arc flash potential by containing and directing the arc flash incident energy away from personnel while maintaining the unit’s physical integrity. This is a Control Engineering 2012 Engineers’ Choice finalist.

The new tiastar MCC line includes the first arc-resistant MCC compliant to ANSI/IEEE C37.20.7. Its criteria for containing and redirecting arc flash incident energy has been successfully witness tested in the presence of UL representatives. The new SmartStart option features plug-and-play functionality that reduces commissioning time with preprogrammed and preconfigured data. High-density designs meeting UL and NEMA standards, while reducing unit size for NEMA 1 through starters, allow for up to a 10% weight reduction and a 25% smaller footprint.
