Klein Tools Digital Circuit Breaker Finder ET310 & AFCI/GFCI Outlet Tester RT310

Klein Tools (www.kleintools.com), for professionals since 1857, introducesa new Digital Circuit Breaker Finder(Cat. No. ET310)and an AFCI/GFCI Outlet Tester(Cat. No. RT310), augmenting Klein Tools existing Electrical Test and Measure product offering. The ET310 Circuit Breaker Finder easily identifies the circuit breakers to which specific electrical fixtures such as outlets or light fittings are connected. The RT310 can identify common wiring problems in standard, AFCI, and GFCI outlets. It also allows you to simulate the fault conditions and test AFCI or GFCI devices. Both tools are designed for use with North American-style grounded electrical outlets.

  • Quickly and accurately locates the correct circuit breaker in a panel corresponding to the circuit to which an electrical outlet or fixture is connected
  • Tester consists of two parts:
    • Transmitter connects directly with the fixture or electrical outlet
    • Receiver scans the panel and locate the corresponding breaker
  • Receiver delivers visual and audible indicators when the correct breaker has been located
  • The Transmitter has a 3-pin plug that can be used with North American-style grounded electrical outlets for 90-120V AC circuits
  • Transmitter incorporates a convenient GFCI outlet tester to inspect the wiring condition at the electrical outlet and test GFCI devices
  • Transmitter docks securely in the receiver for convenient storage as a single item when not in use
  • To conserve battery life, receiver turns off automatically after three minutes without being used.
  • Transmitter is powered by the circuit when connected to the electrical outlet or fixture
  • Low battery indicator and easily accessible battery compartment; receiver uses one 9V battery
  • With 2.0 m (2.m) drop protection, rugged design withstands harsh conditions on the job site
  • Safety rating CAT II 120V
  • Measurement Category II is applicable to test and measuring circuits connected directly to utilization points (socket outlets and similar points) of the low-voltage MAINS installation
  • Included: transmitter, receiver, manual, 9V battery (for receiver), and user manual
  • Additional accessories to connect to other electrical fixtures are sold separately(Cat. No. 69411)

A circuit breaker finder can make it easy to locate breakers in busy panels. An electrician can quickly find the right breaker for a fixture outlet and connect it correctly every time. This is a huge benefit. This also saves time and allows the electrician to avoid powering down circuits that are not necessary for the task at hand.

    • Tests AFCI devices by simulating arc fault conditions
    • Tests GFCI devices by simulating ground fault conditions
  • Patent-pending technology that can detect a dual-open fault in a wiring system with simultaneously open neutral and open ground wires.
  • The tester gives a clear visual indication of the condition of the wiring at the outlet.
  • Three-pin plug for use on North American-style grounded electrical outlets in 120V AC circuits
  • 25 cm (254mm) flexible electric cord for easy access in difficult to reach places.
  • Battery life is conserved by turning off the auto poweroff after 2 minutes of inactivity
  • Low battery indicator and easily accessible battery compartment; includes 3 x 1.5V AAA batteries
  • Built to withstand a 2.0 m (2 m) drop
  • CATIII 135V safety rating
  • Measurement category III applies to circuits used to measure and test the low-voltage MAINS installations in buildings.
  • Klein Tools’ patent-pending design for the AFCI test method was created exclusively for Klein Tools

The detection of wiring faults in electrical outlets is an application of paramount importance to electricians, says OFlaherty. Dual open ground and open neutral faults can make this difficult. Klein Tools new AFCI/GFCI Outlet Tester addresses this circumstance and can identify the dual open fault condition as well as detect the presence of the energized live wire (patent-pending). In addition to testing standard GFCI devices and 30mA ground-fault devices by simulating ground faults, the RT310 can also test AFCI devices by simulating arc-fault conditions. The RT310 is a one-stop outlet testing solution ideally suitable for electricians, facilities and maintenance professionals and technicians engaged in residential commercial and industrial electrical work.

We are proud to introduce both the ET310 and RT310 to Klein Tools test and measurement portfolio.
