Small, Versatile Remote Controlled Circuit Breaker Design Complements Next Generation Aircraft System Requirements

A new remote controlled circuit breaker (RCCB) has been developed to meet needs of both present and future aircraft electrical systems. The small size and actuation versatility of the new RCCB design allows system designers improved flexibility in designing distribution systems which reduce wire weight and is compatible with computerized bus management concepts.

Conventional RCCB's are applied in systems that supply trip and reset signals from the flight deck via hard wired indicating and control units. The necessary logic circuitry is contained in each RCCB. New microprocessor controlled systems would provide operation from centralized logic via MUX busing to satellite interface modules. RCCB's used in this approach are inherently simpler, lighter, more reliable and economical.
