Introduction to 0674008.DRT4

The 0674008.DRT4 is a 4-port directional fused protector that provides a reliable, cost-effective solution of protection against transient overvoltage and current surges generated by lightning, static electricity, or induced fault currents. Its split case design allows for installation either in a non-metallic enclosure (such as a UT for Telephone) or directly in additional short distance remote application.

Application Fields for 0674008.DRT4

Due to this split-case design, the 0674008.DRT4 is commonly used in a variety of application fields. The 0674008.DRT4 is ideal for protection in telecommunication and CATV installations, as the four-pair fused protector protects externally connected lines to minimize potential damage from surges. This product is also suitable for applications such as security equipment and industrial machinery, where surge protection is necessary for the reliable operation of sensitive equipment and components.

Working Principle of 0674008.DRT4

The 0674008.DRT4 utilizes a Miniature Circuit Breaker (MCB) with four-pairs of separate replaceable Insert-style Fuse Links (FSL) that provide superior-level surge protection. To ensure that the 0674008.DRT4 is sufficient to protect against high voltage spikes, the MCB is designed to guard against overvoltage and current peaks of up to 400 volts/50 kA. The Insert-style Fuse Links (FSL) in the 0674008.DRT4 are designed to self-open in case of an overload or short circuit in the line. This feature provides circuit isolation and prevents further damage or potential overcurrent conditions. The isolating mechanism of the fuse links makes it possible to reset the circuit after the surge has been identified and located. The 0674008.DRT4 is equipped with surge indicator LEDs which allow testers to quickly identify surge-caused damage and locate the particular line in which it occurred. This feature eliminates the traditional hassle of time-consuming testing and subsequent diagnosis of possible surge-caused damage.

Conclusion

In conclusion, the 0674008.DRT4 is a 4-port directional fused protector that provides reliable and cost-effective surge protection in telecommunication and CATV installations, as well as in security systems and industrial machinery. Its four-pair Replaceable Insert-style Fuse Links (FSL) are designed to self-open in case of an overload or short circuit in the line, while its MCB ensures protection against overvoltage up to 400 volts/50kA. The 0674008.DRT4 also features a quick-surge indicator, which helps testers to identify and locate the particular line affected by the surge.
