Phase Sequence Meter Manufacturer,Supplier and Exporter in India
Product Code : EL-LE-11734
Jlab Export is a leading Phase Sequence Meter Manufacturer,and suppliers in India
Phase Sequence Meter (code EL-LE-11734) is a battery-powered tester, model JL174/024, that shows the phase sequence of a three-phase supply, flags a missing phase and indicates motor rotation, each on its own LED. It works on 90–600 V AC across 15–400 Hz. JLab makes this compact tester in Ambala, India, for electricians and machine labs.

Why Phase Order Matters
Swapping any two lines of a three-phase supply reverses an induction motor. Checking the sequence before coupling a motor to a pump, conveyor or lathe avoids running the machine backwards. The phase-loss LED picks up a blown fuse or broken line that would otherwise leave a motor running on two phases.
Using the Tester
Connect its three inputs to the three lines in order and read the sequence LED; with an operating current below 3 mA it draws very little from the circuit. At 123 x 71 x 29 mm and 180 g it fits a tool pouch, and a single 9 V (6F22) battery powers it.
