LP2000 Vacuum Circuit Protector

The LP2000 vacuum circuit protector is designed to replace mechanical circuit breakers now used by the mining and utility industries. The accuracy and flexibility in the LP2000 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. Rated 1000 volts AC at 475 amps continuous. FLA can be adjusted from 475 amps down to 225 amps at 1 amp resolution. Other voltage and ampere ratings available.
