Safran RCCBs: Advanced power protection

10 November 2025

In today’s aerospace and defense environments, electrical systems demand compact, reliable and intelligent protection solutions. Safran Power USA has set the industry standard with their Remote Controlled Circuit Breakers (RCCBs): a technology that combines the best features of a traditional circuit breaker and a relay into a single, lightweight unit. As an authorized distributor and supply chain partner, FDH Electronics helps to deliver these high-performance products directly to customers worldwide.

Safran RCCBs are more than just protective devices, they are versatile, space- and weight-saving solutions designed for demanding applications. Here are a few reasons they stand out:

    • Dual functionality: RCCBs protect electrical systems during circuit or load breakdown while also allowing remote on/off control reset from the flight deck. The RCCB also serves as a relay, which is rated for 50,000 cycles.
    • Weight and cost savings: By eliminating long runs of heavy cables between the cockpit and remote relays, Safran RCCBs promote more efficient power distribution and reduce overall system weight.
    • Cockpit space optimization: With RCCBs, large circuit breakers are removed from the cockpit while still enabling pilots full load control.
    • Qualified to MIL-PRF-83383: Safran RCCBs meet stringent military performance requirements, making them ideal for aerospace, defense and other mission-critical applications.
    • Proven durability: Designed to withstand extreme vibration, shock, temperature, altitude and electromagnetic interference (EMI)/radio frequency interference (RFI) conditions, Safran RCCBs deliver long-lasting reliability in harsh environments.

Applications across aerospace and defense Safran RCCBs are widely adopted in aircraft power distribution systems, where performance, safety and space efficiency are paramount. Their use extends across:

  • Commercial and military aircraft platforms
  • Space and satellite systems
  • Advanced defense electronics
  • Other high-reliability applications requiring remote-controlled power management
