Mitsubishi Electric Automation, Inc. Molded Case Circuit Breakers

The main WS-V range is designed to IEC standards * and is intended to service a world market demanding ever higher interrupting capacity in smaller packages. Fixed and Adjustable Types in sizes from 5A up to 250A are available, both thermally adjustable and electronic. Main Features: • WS-V is an all-new design that uses internal gas pressure as well as the electromagnetic force generated during a fault to give higher interrupt ratings and better repeat performance ("Ics = Icu") * • Frame sizes have been harmonized to simply panel installation • 250A frame breakers are 26% smaller than the previous generation • Electronic versions are available with a built in display option that provides detailed information about the power supply. • Adjustable versions of WS-V are 26% smaller than the previous WSS series. * Note: The WS-V breakers are currnetly not UL listed. Use the WS series breakers for UL489 applications. A limited range of UL versions of WS-V will be available by the end of 2011.
