RELAY (P/N qr50h) - As Removed

The qr50h is an aircraft relay that switches higher-current circuits using low-current electrical input. This electromagnetically actuated switch controls power to avionics, lighting, and other aircraft systems from the flight deck or autopilot commands. The relay meets MIL‑PRF‑6106 aerospace standards and is qualified on the DLA Qualified Products List for reliability in demanding flight environments.

Installation requires mounting per the aircraft maintenance manual with wire sizing and control voltage matched to the specific circuit requirements. Proper relay selection ensures safe system operation and protection against electrical overload.
