Knopp type k-3 phase sequence indicator with case
Used Knopp Phase Sequence Indicator K-3 with case.
The Knopp K-3 Phase Sequence Indicator by is used to determine the phase sequence (A-B-C or C-B-A) or direction of rotation in three-phase motors (A-B-C is clockwise rotation).
The primary function of the K-3 Phase Sequence Indicator is to indicate the order of succession in time of the different voltage peaks of a multi-phase supply. In addition, the Knopp K-3 Phase Sequence Indicator enables one to make continuity tests.
It is a valuable testing instrument in diverse fields such as polyphase power applications, and is employed by line and installation crews for public utilitiy systems and industrial-plant electrical departments.
* Test leads are 36 inches in length and color-coded (red (A), white (B), and blue (C)) for easy connection.
* The K-3 Phase Sequence Indicator is of the rotating-disk design; there are no lights to burn out.
* All internal connections are soldered and there are no exposed metal parts on the housing.
* A rugged cordura carrying case is available for this fine instrument. (see below)
* The K-3 is designed for operation from 25 to 60 Hertz and from 60 to 600 Volts.
