Ideal Industries Three-Phase Motor Rotation Tester, 61-521

Overview

The Ideal Industries 61-521 Three-Phase/Motor Rotation Tester is an essential diagnostic instrument for electricians and maintenance technicians working with three-phase electrical systems. This compact, handheld tester identifies three-phase sequence, indicates motor rotation direction, and detects open phases — critical functions for ensuring proper motor operation and preventing equipment damage caused by incorrect phase connections.

Designed for professional use in industrial and commercial environments, the 61-521 features CAT III 600V safety rating and intuitive LED indicators that clearly display clockwise (L1-L2-L3) or counter-clockwise (L2-L1-L3) rotation. A built-in low battery indicator ensures reliable readings, while color-coded test leads (red, white/yellow, blue/black) simplify hookup and reduce connection errors.
