Frequently Asked Questions

What is the HDE Phase Sequence Tester used for?

The HDE Phase Sequence Tester (MPN K-7-1) is used to verify the correct phase rotation (clockwise or counterclockwise) in three-phase electrical systems. It is essential for commissioning motors, generators, and other three-phase equipment to prevent damage from incorrect phasing.

What are the specifications of the HDE Phase Sequence Tester?

The HDE Phase Sequence Tester operates from 25 Hz to 60 Hz and 60 V to 600 V. It is designed for three-phase systems, uses test leads for circuit connection, and has no display. The brand is HDE and the manufacturer part number is K-7-1.

Where to buy the HDE Phase Sequence Tester worldwide?

You can source the HDE Phase Sequence Tester (K-7-1) through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring the tester reaches your facility reliably.

How to use the HDE Phase Sequence Tester safely?

To use the HDE Phase Sequence Tester, connect the test leads to the three-phase lines following the color-coded or labeled terminals. Ensure the voltage and frequency are within the 60 V to 600 V and 25 Hz to 60 Hz range. Always de-energize circuits before connecting and follow standard electrical safety practices.
