Announcement: Eurotherm® Joins Watlow® - Read Press Release

ASPYRE® Intelligent Power Controller

Effective in April 2006 through UL® 508A, the National Electric Code® (NEC®) requires that electrical panel assemblies be marked with the available fault current or Short-Circuit Current Rating (SCCR).The SCCR rating must be marked on all industrial electrical panels and will be rated at the level of the lowest SCCR component
