True Mission Critical Performance
True mission critical performance is achieved when RPP components are designed to trip selectively; AND have the property of current-limiting or high-speed tripping.
Selective Tripping means that when a fault occurs anywhere in the distribution system, one and only one breaker will trip. That breaker will always be located upstream and closest to the fault.
High Speed Branch Circuit Breakers
High-speed current limiting circuit breakers provide a high reliability tripping mechanism that is designed to safeguard cables and wires from excessive overheating. The breakers consist of a current limiting element that safely diverts the energy from the fault away from the contacts, to protect upstream devices.
