Klein Tools ET350 4-in-1 Digital Circuit Breaker Finder, Outlet Analyzer, Non-Contact Voltage Tester, and GFCI Checker with Learn/Locate Mode, Backlit LCD, and LED Worklight
Product Description
Klein Tools ET350 4-in-1 Digital Circuit Breaker Finder
The Klein Tools ET350 combines four essential electrical testing functions in a single handheld unit. It serves as a digital circuit breaker finder, outlet analyzer, non‑contact voltage tester, and GFCI checker, all within an ergonomic design. The integrated learn/locate mode streamlines the process of identifying circuit connections, while the backlit LCD provides clear visibility in low‑light conditions. An LED worklight is also built into the tool, offering illumination for detailed work or in poorly lit spaces.
Digital Circuit Breaker Finder
With the circuit breaker finder capability, the ET350 helps locate the breaker that supplies power to a particular outlet or fixture. The device detects the presence of voltage in the outlet’s circuit, enabling the user to identify the corresponding breaker quickly. This function reduces the time needed to perform routine electrical maintenance or troubleshooting.
Outlet Analyzer
The outlet analyzer feature tests the condition of standard electrical outlets. By measuring voltage, polarity, and outlet condition, the tool can determine whether an outlet is functioning correctly or requires repair. The analyzer also checks for correct grounding, providing a clear indication of outlet integrity.
Non‑Contact Voltage Tester
The non‑contact voltage tester allows for safe detection of live wires or components without direct contact. When an energized conductor is brought near the probe, the tester emits a visual and audible cue. This function is useful for identifying live circuits before proceeding with wiring work or repairs.
GFCI Checker
The GFCI checker evaluates the performance of Ground‑Fault Circuit Interrupters. By applying a simulated fault and observing the GFCI’s response, the tool verifies that the device will trip when necessary. This capability ensures that GFCI outlets remain functional, contributing to electrical safety.
Learn/Locate Mode
Learn/locate mode is designed to simplify the process of identifying which breaker controls a particular outlet or appliance. The user first activates the learn mode, then the device records the voltage pattern of the selected circuit. When the locate mode is engaged, the tool indicates which breaker corresponds to the learned pattern, facilitating efficient circuit mapping.
Backlit LCD Display
The backlit LCD screen provides readable status information in dark environments. Users can view voltage readings, test results, and operational modes without the need for external light sources. The display is clear and easy to interpret, supporting accurate diagnostics during electrical work.
LED Worklight
An integrated LED worklight offers a focused beam for inspecting outlets, breakers, and wiring. The light can be switched on or off as needed, offering flexibility during both day and night tasks. Its compact size ensures it does not obstruct the user’s view or interfere with other tools.
Compact, One‑Piece Design
The ET350’s single‑piece construction provides a straightforward, reliable user experience. All functions are accessible through a simple interface, and the tool’s form factor is designed to fit comfortably in a hand. The device’s layout allows for quick toggling between test modes without complicated controls.
Safety Considerations
While the tool offers multiple testing functions, it is intended for use by individuals familiar with electrical work. The device’s non‑contact voltage detection feature helps prevent accidental contact with live circuits, but users should follow standard safety practices when working around electricity.
Applications
- Identifying the breaker that supplies power to an outlet, switch, or fixture.
- Testing outlet polarity, voltage, and grounding.
- Detecting live conductors before wire removal or installation.
- Verifying the operation of GFCI outlets and devices.
- Providing illumination for detailed electrical inspections.
The Klein Tools ET350 is a versatile diagnostic instrument that consolidates several testing functions into one compact tool. Its design emphasizes clarity, safety, and efficiency for electrical professionals and DIY enthusiasts alike. By integrating circuit finding, outlet analysis, voltage detection, and GFCI verification, the ET350 supports a range of tasks that require accurate electrical measurements and reliable circuit identification.
