SHUNT (P/N cm2916-125) - New Surplus

The cm2916-125 is an aircraft electrical shunt for ammeter and loadmeter circuits. This precision resistor measures electrical current by producing a calibrated 50 millivolt drop across its terminals, allowing the connected indicator to display charge/discharge or alternator-load status. Installed in series with the high-current circuit path, the shunt's sense leads connect to the meter for accurate current indication.

Commonly found in general aviation electrical systems, the component requires installation per aircraft wiring diagrams and FAA AC 43.13-1B practices. Verify the 50 mV shunt requirement before installation to ensure proper indicator compatibility.
