Elbro Drehfeld-Tester Testy 3000 – Portable Phase Rotation Tester for Industrial Electrical Systems
The Elbro Testy 3000 is a compact Drehfeld-Tester (phase rotation tester) designed for quick and reliable verification of rotating field direction in three-phase electrical systems. With a wide voltage range and a built-in LED warning lamp, it provides immediate visual feedback on correct or reversed phase sequence.
LED-Warnlampe delivers instant visual indication of phase rotation direction
Wide measurement range of 100–700V covers most industrial and workshop three-phase supplies
Compact, lightweight design at 343 g ensures easy handling and portability in the field
Suitable for electricians, maintenance technicians, and electrical engineers working on live panels
Das zeichnet den Elbro Testy 3000 aus
Unlike basic continuity testers, the Testy 3000 specifically detects the direction of the rotating magnetic field in three-phase motors and systems. This capability is essential before connecting motors to prevent reverse rotation, which can damage equipment or create safety hazards. The integrated LED warning lamp eliminates the need for a separate indicator, streamlining the testing process on site.
Ideal für...
Electricians and maintenance teams working in industrial settings, workshops, and building electrical installations. The device is particularly suited for technicians who need to verify phase rotation quickly before commissioning three-phase motors, control cabinets, or distribution boards.
