Series 70 eRPP Selective Trip Coordination Testing Complete
Chagrin Falls, Ohio (November 20, 2007) LayerZero Power Systems, Inc. has completed key testing of a Selective Trip Coordination technology, a method to ensure that when a downstream fault occurs in a Remote Power Panel, only the breaker closest to the fault trips. LayerZero high speed branch circuit breakers are designed for high speed selective tripping, designed to open in 2-4 milliseconds, protecting the main breakers, and providing coordination up to 25kAIC.
"The successful test results represent a milestone in LayerZero history", stated a company representative, "Selective Trip Coordination will become increasingly more important as data centers increase densities, zero-crossing breakers take up to three cycles to trip, and are simply not sufficient in high power environments."
Selective tripping is a high-reliability mechanism to ensure that the main breaker does not trip when a fault occurs at the branch level, protecting a downstream fault from taking out an entire power panel. Selective Trip Coordination quickly extinguishes the arc, driving energy away from contacts, and protecting cables from excessive heating. Designed for mission-critical applications, high speed branch circuit breakers with selective trip coordination is necessary for critical load protection.
