Major Tech Circuit Breaker Finder with RCD Test MT190

Description

Fast, Accurate Circuit Tracing for Busy Electrical Worksites

The Major Tech MT190 Circuit Breaker Finder takes the guesswork out of circuit identification on live 230VAC systems. Designed for licensed electricians and contractors, it quickly locates the correct MCB or fuse at the distribution board using automatic signal detection. The transmitter sends a clear signal through the circuit while the receiver instantly responds with visual LED cues and a continuous audible tone, allowing fast and confident breaker isolation. With self-calibrating microprocessor technology and automatic scanning, it helps reduce troubleshooting time on site and keeps jobs moving efficiently.

Built-In Safety Testing and Reliable Wiring Verification

More than just a breaker finder, the MT190 includes a built-in 30mA RCD test function directly in the transmitter for added safety checks during installation and maintenance work. It also provides clear correct wiring indication with LED feedback, helping identify open ground, reverse polarity, open live, open neutral, and wiring faults before energising circuits. Rated CAT III 600V, this tool is built for safe use in residential, commercial, and light industrial environments where compliance and accuracy matter on every job.

Practical Design for Real-World Trade Efficiency

Built for everyday trade use, the MT190 features a simple transmitter-and-receiver setup that’s quick to deploy on site. The receiver offers straightforward On/Reset/Off controls, while the audible and visual signals make identification fast even in noisy environments. Compact, lightweight, and battery powered, it comes ready with a carrying case and instructions so it’s easy to transport between jobs. Whether you’re fault-finding, upgrading switchboards, or doing maintenance work, this tool helps cut downtime and improve productivity.
