Southwire NCV Detector for 100-600V AC

The Southwire 40116N AC non-contact voltage (NCV) pen tester is a valuable addition to your tool bag, designed to identify the presence of voltage during electrical work. This versatile device can detect voltage in a variety of electrical components, including wires, light switches, circuit breakers, outlets, and light fixtures.

To use the 40116N, simply press the On button, and the detection tip will glow green, indicating that the device is ready for use. Then, 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, while the NCV will also emit a loud beep, alerting you to the presence of voltage.

The 40116N can also be inserted directly into electrical outlets to verify their operation, providing a convenient way to ensure that the outlet is functioning properly. Additionally, the device features a built-in focused LED flashlight, which can be used to illuminate dark areas, enhancing the overall convenience and usability of the tester.

To conserve battery power, the 40116N is equipped with an auto power-off feature that turns the device off after 5 minutes of inactivity. This feature helps to extend the battery life, ensuring that the tester is always ready for use.

As an added safety feature, the 40116N has a low-battery self-test function that periodically checks the condition of the batteries. If the battery voltage becomes too low, the self-test circuit will automatically turn off the non-contact voltage detector until the batteries are replaced, helping to prevent the risk of false readings or malfunctions.

The Southwire 40116N is UL listed, ensuring that it meets the highest safety standards. It is not, however, designed for use with Tamper Resistant (TR) outlets, which may require a different type of tester.

In summary, the Southwire 40116N AC non-contact voltage (NCV) pen tester is a versatile and reliable tool that offers both audible and visual indication of AC voltage from 100 to 600V, with a CAT IV 600V safety rating. Its increased battery life, built-in flashlight, and self-test function make it a valuable addition to any electrician's or DIY enthusiast's tool bag.
