Product Description

Motor and Phase Rotation Tester


The Motor and Phase Rotation Tester permits the electrical contractor or industrial maintenance electrician to permanently connect and tape the terminals of the motor being installed, without having to first energize the motor by a temporary hookup from a power source, if available, to determine motor rotation. Therefore, the test set eliminates the need for temporary connections that can be time consuming, costly and quite hazardous, particularly where many large, high-voltage motors are involved. Also, certain types of drives should never be rotated in the wrong direction. In such cases, the temporary hookup or trial method, having a fifty-fifty chance of being wrong, can do serious harm. The three motor leads on the left side of the test set are for attachment to the terminals of the motor being tested for rotation determination. Fuses are inserted in the motor A and C test leads as protection in the event the user accidentally touches these leads to an energized circuit. These standard fuses are easily removed and replaced from their panel-mounted holders. The three lines leading to the right of the test set are for direct attachment to energized ac power systems up to 600 volts to determine the system phase sequence. 


■ Determines rotation direction of one-, two- or threephase motors before connection to line

■ Determines phase rotation or sequence of energized power circuits

■ Determines polarity of instrument and power transformers

■ Determines phase/polarity of unmarked motor windings

■ Identifies true phase sequence of energized ac power lines up to 600 volts (Higher voltages can be tested by interposing a step-down transformer.) 



Input (specify one) : 50/60 Hz or 25/50/60/400 Hz

Enclosure : The test set is enclosed in an ABS high-impact plastic case that has a handle and hinged, removable lid. The deep lid provides storage space for the instruction manual and test leads.
