High-Performance 3-Phase Testers

Testing and tagging of 3-phase portable electrical equipment is a mandatory requirement under Australian Standard AS/NZS 3760, especially in commercial and industrial environments. Unlike single-phase appliances, 3-phase equipment operates at higher power levels, typically ranging from 20 to 32 amps with 4 or 5 pins, making specialised testers essential for safe and accurate inspections.

Our 3-phase appliance testers are specifically designed to test insulation resistance, polarity, and earth continuity on 3-phase tools, machinery, and other heavy-duty equipment. Whether you're a licensed electrician, maintenance manager, or test and tag technician, these testers help ensure compliance, reduce electrical risks, and maintain a safe work environment.

We offer models compatible with common 20A and 32A plugs, as well as adaptors to suit a variety of configurations. Each unit is rugged, easy to use, and built for reliability in the field. Plus, many of our testers integrate seamlessly with your existing test and tag systems and accessories.
