The Model NTS-300A is a self-contained, two-piece test set designed for complete testing of General Electric and Westinghouse secondary network protectors.
The two-piece design of Model NTS-300A enables the user to transport the unit and easily lower it into a manhole.
The unit performs operational tests on 216 and 480 volt network protectors; it can also be used for trouble-shooting tests on the operating mechanism and on both electromechanical and solid-state network relays.
