What is the advantage of having a UL Listed reactor?

The UL Listed mark provides a higher level of acceptability. Reactors that are UL Listed meet the same safety standards but are viewed differently by Underwriters Laboratories. They consider UL Listed products as being complete end-products, versus components that will be used as part of a larger system. While a UL Recognized reactor may adequately address a system’s needs, the field inspection may require UL Listed products in a given installation. UL Listed Reactors meet a broad range of installation requirements. UL Recognized products may require an addition to a user’s UL file, whereas UL Listed products may not.
