description southwire ncv detector 50 600v ac pro southwire pro 40136n ac non-contact voltage (ncv) pen tester a valuable addition to your tool bag. use it whenever you perform electrical work to identify where voltage is present. detects voltage in wires, light switches, circuit breakers, outlets and light fixtures. press the on button and the detection tip glows green. move the detector tip close to the electrical wire or device being tested. if voltage is detected, the detection tip will change from green to red and begin flashing. the ncv will also beep loudly. the 40136n can also be inserted directly into electrical outlets to verify operation. all southwire non-contact voltage detectors come with a built-in focused led flashlight so you can illuminate dark areas. auto power off feature helps conserve battery power. silent mode allows you to silence the beeper for quiet areas like hospitals, office buildings, and schools. as an added safety feature, the 40136n has a low-battery self test which periodically checks the condition of the batteries. if battery voltage becomes too low, the self-test circuit turn off the non-contact voltage detector until the batteries are replaced. the 40136n is ul listed. not designed for use with tamper resistant (tr) outlets. california proposition 65 warning. features audible and visual indication of ac voltage from 50 to 600v increased battery life auto power off after 5 minutes of inactivity proximity indication beeping and flash rate increases as tester gets closer to the voltage source built-in flashlight for added convenience cat iv 600v safety rating specifications ac voltage 50 to 600 acme tools brand name southwire acme tools part number 40136n assembled depth (in) 0.99 assembled height (in) 6.23 assembled weight (lbs) 0.16 assembled width (in) 0.83 battery quantity required 2 battery size aaa california proposition 65 warning required yes capacitance capable no case included no color / finish copper continuity beeper no country of origin china data hold no dc polarity indicator no dc voltage n/a digital display not required electronic yes globaltradeitemnumber (gtin) 00032886963070 height (in) 6.23 internet product code (ipc) f9bf9cdc9c9 manufacturer warranty 2 years material double molded plastic package contents 40136n ncv detector 50-600v ac pro package depth 1.58 package height 8.661417322834646 package weight 0.181 package weight (lbs) 0.181 safety rating cat iv 600v, ul listed tester type non-contact tests continuity no upc 032886963070 voltage compatibility ac only
