The Kussmaul Auto Current A-6 is a current-sensing and auxiliary-input control device designed to provide remote indication when monitored electrical loads or connected switches are activated. Designed for fire apparatus, ambulances, rescue vehicles, command vehicles, and other specialty vehicle electrical systems, the Auto Current A-6 simplifies warning circuits by allowing a single indicator to monitor multiple electrical loads and auxiliary switches.
The Auto Current A-6 senses current flow from 0.10 to 4 amps through electrical loads connected in series with the sensing terminals. An additional ground-activated auxiliary input can be connected to multiple switches wired in parallel, allowing any connected switch to activate the output independently of the current-sensing circuit. When activated, the output relay cycles ON and OFF to create a flashing warning signal. This combination makes the Auto Current A-6 ideal for DO NOT MOVE VEHICLE indicators, open compartment door detection, and other emergency vehicle warning applications. The standard unit supplies +12 volts to the connected indicator, while optional -G configurations are available for applications requiring the indicator to be operated by grounding.
