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.
