Major Tech Circuit Breaker Finder

The MT190 Circuit Breaker Finder by Major Tech is an advanced tool designed for electricians and maintenance professionals to accurately locate circuit breakers and fuses on live electrical circuits. The unit consists of a Transmitter which plugs into the socket on the circuit you wish to isolate and a Receiver Scanner. The Transmitter sends signals along the cable to the distribution board, the operator simply runs the Receiver Scanner along the circuit breakers or fuses, and the scanner will automatically identify the correct breaker by means of a green LED and a continuous buzzer tone. 

Key Features:

• Automatic Scanning Technology: Quickly and accurately identifies circuit breakers and fuses, minimizing the time spent on electrical troubleshooting.
• Self-Calibrating Microprocessor: Ensures precise and reliable operation without manual adjustments.
• Operates on 230V AC Circuits: Designed for 200-240V AC, 50Hz electrical systems, making it suitable for residential and commercial applications.
• Built-in 30mA RCD (ELCB) Test Function: Tests residual current devices (RCDs) to verify their functionality, enhancing safety compliance.
• Wiring Condition Indicator: The transmitter includes an LED display that helps diagnose socket wiring issues, including:
  • Correct Wiring
  • Open Ground
  • Reverse Polarity
  • Open Live
  • Open Neutral
  • Reverse Live and Ground
• Visual and Audible Indicators: The receiver scanner provides a green LED indicator and a continuous buzzer tone when the correct breaker is identified.
• Compact and Lightweight: The receiver measures 196 x 55 x 36mm and weighs only 148g, making it highly portable.
