Major Tech 220V ELCB & Polarity Tester MT310

Description

Fast, Accurate Testing for Everyday Electrical Work

The MT310 is built for electricians who need quick, reliable results on-site without wasting time on complex setups. Simply plug it into a standard 230V outlet and instantly check socket wiring, polarity, and earth leakage performance. The clear LCD display shows AC voltage readings at a glance, helping you confirm circuit conditions in seconds.

With adjustable test current settings from 10mA to 35mA, you can easily simulate leakage conditions to identify faults or help prevent nuisance tripping. Whether you’re troubleshooting residential circuits or verifying installations on commercial jobs, this tester helps speed up diagnostics and keeps your workflow moving.

Reliable Safety Compliance You Can Trust

Designed with trade safety in mind, the MT310 supports CAT III 600V and CAT IV 300V ratings, giving you confidence when testing live circuits. The bright neon indicators provide immediate visual confirmation of correct wiring status, helping reduce errors before energising equipment.

Built to meet IEC61010-1 safety standards, it delivers dependable performance across 50/60Hz systems commonly found on Australian sites. The double-injection rubber housing adds durability for everyday use on busy job sites, protecting the unit from knocks and handling wear.

Built for Trade Efficiency and Job Site Convenience

Lightweight and compact, the MT310 is easy to carry in your tool bag and quick to deploy when you need fast checks between tasks. The separate test button simplifies operation, while fixed current selection makes switching between test conditions straightforward and efficient.

For electricians working under tight project deadlines, this tester reduces time spent fault-finding and helps ensure installations are compliant before handover. It’s a practical diagnostic tool for maintaining productivity across residential, commercial, and maintenance work.
