Overview

The ATOPLEE 3 Phase Sequence Presence Rotation Tester is a compact, handheld tool designed for electricians, panel builders, and maintenance techs. It helps you quickly verify the order of phases in three‑phase AC systems and alerts you with a clear LED indication and a buzzer when the correct sequence is detected. With a broad voltage range and built‑in protection, it serves as a versatile companion for on‑site checks.

Key capabilities

  • Voltage range: 60 V to 600 V AC for common 3‑phase installations
  • Frequency compatibility: 20 Hz to 400 Hz, covering most commercial and industrial networks
  • Test leads: approximately 1 meter long for flexible access to panels
  • Protection: up to 2000 V, with impulse tolerance of 4000 V during probing
  • Indication: LED plus audible buzzer to show phase presence and rotation
  • Usage limits: up to 60 minutes continuous use at 60 V, and up to 4 minutes at 600 V

Practical uses

  • Verify correct phase sequence when wiring new motors or starters
  • Check panels during commissioning to prevent mis-wiring errors
  • Perform quick field checks on existing equipment before maintenance tasks
  • Educate apprentices with a clear visual and audible feedback during training

How it works

Connect the test leads to the circuit under test, observe the LED indicators, and listen for the buzzer. A confirmed phase rotation is signaled by the corresponding LED pattern and audible cue, enabling fast, confident decisions on site.

Durability and safety

Designed for practical field use, it provides a compact form factor with essential protection. The device’s ratings offer confidence when probing 60 Hz and other common industrial frequencies, without making guarantees about outcomes.

Note: Always follow safety guidelines and power-down procedures before connecting test leads to live circuits.
