PRM-2 & PRM-3
Phase Sequence & Motor Rotation Tester
Phase sequence testing is crucial for some of the three-phase
loads, whenever they need to be connected to the electrical
system. Improper connection of three-phase motors may lead
to reverse rotation, and as a result it may damage equipment
powered by a motor. Amprobe Phase Sequence and Motor
Rotation Testers are used to assure proper and safe connec-
tion of the electrical equipment on three-phase systems.
• Phase sequence indication of the three phase
electrical systems
• Phase voltage loss or voltage sag indication
• Check for normal or reversed phases
• Three phase motor rotation indication
(PRM-3 only)
• Extremely simple to use
• CAT III 600V
