4-in-1 Digital Circuit Breaker Finder

Electrical troubleshooting is now more efficient thanks to the new Klein Tools ET350 4-in-1 Digital Circuit Breaker Finder, a versatile instrument designed to simplify several essential testing tasks with a single device.

Instead of carrying multiple testers, electricians can use the ET350 to quickly identify the correct circuit breaker, verify outlet wiring, perform non-contact voltage detection, and illuminate dark workspaces with its integrated LED work light.

One of its standout features is Learn Mode, which scans the electrical panel and automatically records breaker locations for faster identification. Once the panel has been mapped, Locate Mode allows users to pinpoint the desired breaker with greater speed and accuracy.

The transmitter also provides valuable outlet diagnostics, helping detect common wiring issues, display voltage information, and evaluate GFCI performance before maintenance begins. In addition, the built-in non-contact voltage tester offers both visual and audible alerts when energized conductors are detected, adding another layer of safety during inspections.

Designed for electrical professionals seeking greater productivity and reliability, the ET350 combines multiple testing capabilities into one compact solution, reducing troubleshooting time while improving efficiency on the jobsite.
