SHUNT (P/N 6220-040) - New Surplus

The 6220-040 is a DC shunt for aircraft panel ammeters that measures electrical current by producing a calibrated millivolt drop across its low-resistance element. Installed in series with alternator or battery leads, it functions as a remote current sensor feeding ammeter readings to the flight deck. This AN-type shunt follows standardized aviation specifications for precise DC bus current monitoring.

Installation requires matching the shunt rating to the ammeter specification and routing per aircraft wiring diagrams and AC 43.13-1B accepted practices. Commonly used in general aviation electrical systems.
