5.0 Choosing the Reduction Setting The Arc Flash Maintenance Switch is an eight position rotary switch that has five unique settings. Setting R5 is repeated four times. From the factory, the Medium Voltage circuit breaker is shipped with the Digitrip unit set to the ...
In an electric circuit supplying AC line current rent to a load (30, 31) from an AC source (26) of given frequency providing repetitive cycles, arc detection is provided by sensing cycle to cycle changes in the AC line current. The AC line current is sampled with a harmonic notch filter...
energy source, the armature is drawn into the electromagnetic coil to close the movable contacts onto the stationary contacts, and after energized with a second energy source, lower than the first energy source, maintains the armature within the electromagnetic coil; and an arc pressure containment ...

An electronic circuit includes a number of sensors structured to detect an arc flash from an uncontrolled arcing fault, and a trigger circuit, responsive to the detected arc flash,
The arc flash trigger circuit, in response to the at least one high-voltage capacitor charging, causes one of the at least one gas discharge tubes to conduct energy to a trigger ribbon, where a trigger current is sent to the trigger ribbon in response to one of the at least one gas ...
