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

As the demand for energy increases, industrial systems are growing. Whether the need is petroleum, natural gas or other sources to generate electricity. As heaters grow in size and power controllers become larger, the thirst for more energy sources will only grow. Likewise, 10 years ago, Watlow’s most powerful power controller switched 500 amps. Today, the ASPYRE® DT SCR power controller can handle an incredible 2,100 amps.
