From the company who builds the popular analog ground fault detector comes the newest phase rotation indicator on the market. No other manufacturer offers a phase rotation indicator like STB's DX2 that will read up to 5kV! The phase rotation indicator is used to determine the phase sequence of three-phase voltages. This meter is most commonly used for phasing-in a power line which has supplied power to motors and plants. It is essential for testing departments of public utility systems for laboratory and field testing. The convenient and durable carrying case allows user to safely transport the unit to wherever the job takes them.
Compact, lightweight instrument designed to save time and energy and eliminate mistakes when connecting loads to polyphase circuits
May be suspended by its numbered test clips and the correct phase sequence of the supply, determined by pressing the switch on the side of the case
May be used interchangeably on 110/220/440/550 volt circuits of either 25 or 60 cycles
Meets specifications of Spec. MIL-1-16103
Weight: 1.25 lbs.
Size: 1.25″ thick and 3.25 ” diameter
Case: Molded bakelite with unbreakable crystal

50109-G-DX2 Phase Rotation Indicator- (modules A and B) will read up to 5kV (4160 systems) and includes heavy duty carrying case.
50109-G-05A Phase Rotation Indicator (module A) may be ordered alone, will read 220v-800v and comes with a soft carrying case
50109-G-05B Bottom piece of DX2-if customer purchases 50109-G-05A and decides later to purchase module B separately in order to test 4160 systems they may do so. The hard case will need to be ordered to accommodate both pieces.
