10.7.2 Line Reactor Specifications
All line reactors are equipped with thermal switches and are looped to the enclosed drive for overtemperature protection. For more
details, refer to the
Control Compartment section. The line reactor configuration varies depending on the enclosure and voltage re-
quired.
