The Line Power Down Time Saver (DTS® II) Feeder Circuit Protector

Line Power is proud to introduce the second generation of the Down Time Saver DTS® II for medium voltage feeder and motor protection.

The benchmark DTS® II design continues to serve the needs of our customers by saving them time and money. Traditional feeder circuit protection designs involve numbers components separately mounted in a fixed environment with numerous cables and wire connecting the circuits together. The more circuits, components and wires involved, the greater the probability of system failure, and time and money lost troubleshooting.

LP-2600-300 Circuit Protector

General
The LP-2600-300 vacuum circuit protector is designed to replace 1000V, 300 amp mechanical circuit breakers now used by the mining industry. The accuracy and flexibility in the LP-2600-300 design provides the electrical engineer (or electrician) the means to monitor actual circuit load conditions and “fine tune” the circuit to reduce “nuisance tripping” while maintaining cable protection. The unit can also be used as a belt or pump controller – replacing the mechanical circuit breaker, control contactor and overcurrent relay. The modeling technique used by the LP-2600-300 provides dynamic protection for loads operating at their design limit.
