NPS-3-BL-T4 is a noninsulated free standing and UL recognized varistor. This type of varistor is primarily used for transient protection. It specializes in the protection of sensitive instrumentation, power supplies, process controls, and other electrical circuits against electrical transients where one or more of the following conditions occur: an open or loose circuit due to a fault or excess current, a short circuit due to an overvoltage condition, a short circuit due to an arc, and a short circuit due to the static charge.

The NPS-3-BL-T4 works in two distinct ways. First, it will collate the voltage across its two terminals and then act on it, either reducing it or blocking it, depending on the severity of the overvoltage or the level of the current. Secondly, it will further absorb any overvoltage or excess current that cannot be eliminated by the first action. This absorption of energy is created through its unique insulation property, as it is capable of encapsulating large amounts of this energy without dissipating it as heat.

The primary application field of the NPS-3-BL-T4 is in electrical protection. It is used to protect sensitive electrical components from overvoltages, undervoltages, and excessive current. NPS-3-BL-T4 has become the go-to solution for most applications that require this kind of protection. Additionally, its insulation property makes it suitable for use in areas where dust, dirt, or other contaminants may be present.

The key features of the NPS-3-BL-T4 varistor that has made it so popular for electrical protection include its capability of handling high currents, its low leakage current, and its wide operational temperature range from -35°C to +135°C. It also has a low dielectric loss and high surge current. The low leakage current makes it suitable for use in sensitive circuits where minimal current dispersal is needed.

Overall, the NPS-3-BL-T4 is an efficient and cost-effective choice for transient protection. Its thick insulation and high surge ratings help to protect electrical components from the damaging effects of overvoltage and excess current. Additionally, it is well-suited for use in contaminated areas due to its insulation properties. This makes it a popular choice for use in a wide variety of applications.
